Industry Background

SRAM, LLDRAM and Bandwidth Engine Market Overview

Virtually all types of high-performance electronic systems incorporate some form of volatile memory. An SRAM is a memory device that retains data as long as power is supplied, without requiring any further user intervention. In contrast, dynamic random access memory, or DRAM, is a memory device that requires user intervention in the form of refresh operations to retain data while power is supplied, due to the capacitive nature of its memory cell.  However, a DRAM memory cell is much smaller than an SRAM memory cell, so several times more DRAM bits than SRAM bits can be implemented in any given unit area of silicon.  The fundamentally different characteristics of SRAM and DRAM memory cells have resulted in the emergence of markedly different architectures for SRAM-based and DRAM-based memory products, and the two types of memory serve different applications. Classically, SRAM-based products have served high performance requirements while DRAM-based products have been used in cost-optimized applications.  Today, SRAM- and DRAM-based products serve both performance and cost-based applications.  As the volatile memory market fragments into a variety of specialized products, more meaningful distinctions between volatile memory products can be made.

There is an increasingly broad variety of volatile memory products on the market, characterized by a number of attributes, such as speed, memory capacity, or density, I/O interface and power consumption. There are several different industry measures of speed:

Historically, SRAMs have been utilized wherever other lower price-per-bit memory technologies have been inadequate. SRAMs demonstrate lower latency and faster random access times relative to DRAMs and other types of memory technologies, but at a higher price-per-bit. Historically, the volatile memory market has had three price-performance points, DRAM at the low end, Fast SRAM at the high end, and slow SRAM in the middle.  Over the past two decades, alternative memory technologies have been introduced to address certain applications that formerly used slow SRAMs. For example, new types of DRAM have displaced slow SRAM in applications such as cell phones.  However, in the networking memory market a technology vacuum formed between Fast SRAMs on

---

 

one end and commodity DRAMs at the other, with no high bandwidth, high transaction rate, moderate capacity, moderate latency, and moderate cost volatile memory product to fill the void. In the past decade, Low latency DRAMs, or LLDRAMs, have been developed to fill that void. Like the slow SRAMs that came before them, LLDRAMs have a much higher price-per-bit than commodity DRAMs (in order to deliver higher transaction rates) but demonstrate slower random access times and longer latencies than Fast SRAMs.

All of these SRAM and DRAM  technologies utilize traditional parallel I/O interfaces that require a significant number of pins. Recently we have partnered with another company to provide a new serial I/O (SerDes) memory device called “Bandwidth Engine” which is fabricated using embedded DRAM technology. The Bandwidth Engine has capacity comparable to LLDRAMs but offers far greater transaction rate and data bandwidth capability (greater even than Fast SRAMs) through its serial interface. It can also execute a variety of read-modify-write operations heretofore unavailable in any other memory device. The networking market is just beginning to take advantage of the unique and powerful capabilities of Bandwidth Engine technology.

The need for increasingly greater capacity, data bandwidth, and transaction rates from the various memory technologies continues unabated as the networking market begins to make preparations for Terabit networking in the latter half of the current decade.  We believe that Fast SRAM, Low Latency DRAM and Bandwidth Engine products, optimized for networking applications, will play an increasingly essential role in enabling continued improvements in network performance.

As a result of the displacement of low performance SRAMs, the total market size for SRAMs is diminishing. However, due to their inherent higher latency characteristics, DRAMs cannot match the random access speed of high-performance SRAMs. Gartner Dataquest divides the SRAM market into segments based on speed. The highest performance segment is comprised of SRAMs that operate at speeds of less than 10 nanoseconds, which we refer to as "Very Fast SRAMs." Very Fast SRAMs are predominantly utilized in high-performance networking and telecommunications equipment.

Increasing Need for Networking Memory Products

Growth in data, voice and video traffic has driven the need for both greater networking bandwidth and more complex routing and switching equipment, resulting in the continued expansion of the networking and telecommunications infrastructure. The continued growth in the level of Internet usage has led to the proliferation of a wide variety of equipment throughout the networking and telecommunications infrastructure, including routers, switches, wireless local area network infrastructure equipment, wireless base stations and network access equipment, and a continuing demand for new equipment with faster and higher performance.  Moving data in and out of high performance volatile memory is the core task of every piece of networking equipment. The access patterns or workload  of most memory arrays used in networking equipment are significantly different from those of memory devices typically used in the computer market, such as the DRAMs used for main storage in PCs. As a result, distinct classes of memory products optimized for the demands of the networking market have been emerging over the last fifteen years. The sharply rising demand for increasing worldwide network performance is expected to drive a continuing need for ever more specialized memory products.  High-performance networking and telecommunications equipment requires a variety of memory types; both SRAM-based and DRAM-based. Some of the required memory arrays are embedded in specialized processors or ASICs but many tasks require more bits than can be accommodated on a processor or ASIC, and must be provided in some form of external volatile memory. SRAM-based and DRAM-based networking memory products address this requirement. For example, in a typical router or switch, multiple networking-optimized memory devices are required to temporarily store, or buffer, data traffic and to provide rapid lookup of information in data tables. As networking equipment must increasingly support advanced traffic content such as Voice over Internet Protocol, or VoIP, video streaming and bi-directional video, demand for even higher performance networking memory is expected to continue to increase.

---

 

Demanding Requirements for Success in the Networking Memory Market

The pressure on networking and telecommunications OEMs to bring higher performance equipment to market rapidly to support not only more traffic but also more advanced traffic content is compounded by the requirement that this new equipment occupy no more space than the equipment it replaces, which results in increased circuit density requirements and the need for lower power operations. In response to these pressures, OEMs have increasingly relied on providers that are capable of rapidly developing and introducing advanced, higher density, low power networking memory. The variety of memory applications within the networking and telecommunications markets has also driven a need for more specialized products available in relatively low volumes. These specialized products include high-speed synchronous memory products implemented in both SRAM and DRAM memory technologies with a range of density, latency and bandwidth capabilities. In general, OEMs prefer to work with a supplier who can address the full range of their high-performance networking memory product requirements and, just as importantly, can offer the technical and logistic support necessary to sustain and accelerate their efforts.

We believe the key success factors for a networking memory vendor are the ability to offer a broad catalog of high-performance, high-quality and high-reliability networking memory products, to continuously introduce new products with higher speeds, lower power and greater densities, to maintain timely availability of prior generations of products for several years after their introductions, and to provide effective logistic and technical support throughout their OEM customers' product development and manufacturing life cycles.

The GSI Solution

We endeavor to address the overall needs of our OEM customers, not only satisfying their immediate requirements for our latest generation, highest performance networking memory, but also providing them with the ongoing long-term support necessary during the entire lives of the systems in which our products are utilized. Accordingly, the key elements of our solution include:

Innovative Product Performance Leadership

High Speed.    Through the use of advanced architectures, design methodologies and silicon process technologies, we have developed a wide variety of high-performance networking memory products. Until recently, all of our products have been SRAM-based, but with increased investment in high performance DRAM-based networking memory products we expect to increase our market share in the overall networking memory market. Our SRAM product line has evolved from BurstRAMs with an average transaction rate of about 0.125 BT/s to our SigmaQuad™-IVe SRAMs (currently scheduled to be available later in 2015) with expected transaction rates up to 2.66 BT/s and data bandwidths up to 192 Gb/s, greater than any other SRAM commercially available today. Our current Low Latency DRAMs deliver transaction rates up to 0.533 BT/s and data bandwidths up to 38 Gb/s, with faster versions  expected to be available later this year. Our new Bandwidth Engine products provide transactions rates exceeding 4 BT/s and data bandwidths up to 400 Gb/s. Our SRAM products can produce data at latencies of 4 to 5 ns while LLDRAM and Bandwidth Engine latencies are  approximately 15 ns. By providing higher performance networking memory, we enable our networking and telecommunications customers to continually design and develop higher performance products that support increasingly complex traffic content.

Low Power Consumption.    Many of our products require significantly less power than comparable products offered by our principal competitors. Because these products utilize less power and generate less heat, the reliability of the networking or telecommunications equipment in which they are employed increases. Furthermore, the low power utilization of our products helps enable OEMs to add capabilities to their systems, which otherwise might not have been possible due to overall system power constraints.

---

 

Process Technology Leadership.    We maintain our own process engineering capability and resources, which are located in close physical proximity to our SRAM wafer manufacturing partner, Taiwan Semiconductor Manufacturing Company, or TSMC. This enhances our ability to work closely with TSMC to develop modifications of the advanced process technologies used in the manufacturing of our Fast SRAMs in order to maximize product performance, optimize yields, lower manufacturing costs and improve quality. Our most advanced 144 and 288 Mb synchronous Very Fast SRAMs are manufactured using 40 nanometer process technology.  Our new LLDRAMs are being produced using 63 nanometer DRAM process technology at Powerchip Technology Corporation, or Powerchip, in Taiwan.

Product Innovation.    We believe that we have established a position as a technology leader in the design and development of Very Fast SRAMs. We were the first supplier to introduce 72-bit-wide SRAMs as single monolithic ICs. In 2010, we were the first supplier to introduce a Fast Synchronous SRAM capable of one billion transactions per second – SigmaQuad-IIIe – whose 1.45 BT/s capability was more than double any other SRAM commercially available at the time.  In early 2015, we further solidified our position as a technology leader by being the first vendor to introduce and ship 288 megabit monolithic SRAMs. In addition, we are the only vendor to offer a full line of Very Fast Synchronous SRAMs that operate and interface at 1.8 to 3.3 volts, giving our OEM customers the ability to use the same product in systems that operate at any voltage within that range. Moreover, we are the only vendor to offer a Very Fast Synchronous SRAM product that operates at 1.8 volts and uses approximately one-half to two-thirds the power of our competitors' 2.5 volt products.  We intend to apply the same approaches we used to take the lead in SRAM-based networking memory to the continued development of our line of DRAM-based networking memory products.

Broad and Readily Available Product Portfolio

Extensive Product Catalog.    The Very Fast SRAM market is highly fragmented in terms of product features and specifications. This is especially true of the networking segment of the fast SRAM market and is becoming true of the LLDRAM segment as well. To meet our OEM customers' diverse needs, we have what we believe is the broadest catalog of Very Fast SRAM products currently available, and our LLDRAM and Bandwidth Engine product lines further expand our position in the networking market. Our product line includes a wide range of devices with varying densities, features, clock speeds, and voltages, as well as several operating temperature ranges and numerous package options in both 5/6 RoHS (leaded) and 6/6 RoHS (lead-free) versions, which are compliant with the European Union's Restriction on the Use of Hazardous Substances Directive 2002/95/EC.

Advanced Feature Sets.    Our products offer features that address a broad range of our networking and telecommunications OEMs' system requirements. Among these features is a JTAG test port, named for the IEEE Joint Test Action Group, which enables post-assembly verification of the connection between our product and an OEM customer's system board, thereby allowing an OEM customer of ours to develop, test and ship their products more rapidly. Additionally, we offer our FLXDrive™ feature, which allows system designers to optimize the signal integrity for any given requirement. We also provide OEMs the ability to employ certain of our products in various modes of operation by using our products' mode control pins, thus increasing the flexibility of those products and their ready availability from our inventory.

Superior Lifetime Availability of Products.    Unlike the market for consumer electronics, the markets in which we compete, particularly the networking and telecommunications markets, generally are characterized by system designs that remain in production for extended periods of time, and maintenance of those systems in the field for even longer periods is critical to their success. Our foundry-based manufacturing strategy, our process technology selections, our master-die design strategy and the design of our packaging, burn-in and test work-flows all contribute to allow us to meet and exceed our guarantee of providing a product life of at least seven years for any new product family we bring to market. These techniques also allow us to keep our delivery lead-times relatively short even for

---

 

specialized, infrequently ordered members of those product families. We believe our approach is better suited to address the needs of our target markets than attempts to apply mass market manufacturing strategies to networking memory products.

Multiple Temperature Grades.    We offer both commercial and industrial temperature grades for all of our products. This ability to perform at specification throughout the industrial temperature range of -40°C to +85°C is critical for memory products used in a broad variety of networking and telecommunications applications, where the operating environments may be harsh. We now also offer a portfolio of off-the-shelf military temperature SRAM products and can also offer military customers additional and extended temperature grades upon request.

Master Die Methodology

Our master die methodology enables multiple product families, and variations thereof, to be manufactured from a single mask set. As a result, based upon the way available die from a wafer are metalized, wire bonded, packaged and tested, from 25 mask sets we have created over 15,000 different products. Using these mask sets, we produce wafers that can be further processed upon customer orders into the final specified product thereby significantly shortening the overall manufacturing time. For example, from a 72 megabit mask set, we can produce three families of 72 megabit SRAM products. Our unique methodology results in the following benefits:

Rapid Order Fulfillment.    We maintain a common pool of wafers that incorporate all available master die. Because we can typically create several different products from a single master die, we can respond to unforecasted customer orders more quickly than our competitors.

Reduced Cost.    Our master die methodology allows us to reduce our costs through the purchase of fewer mask sets by allowing faster and less expensive internal product qualifications, by enabling more cost-efficient use of engineering resources and by reducing the incidence of obsolete inventory.

Customer Responsiveness

Customer-driven Solutions.    We work closely with leading networking and telecommunications OEMs, as well as their chip-set suppliers, to better anticipate their requirements and to rapidly develop and implement solutions that allow them to meet their specific product performance objectives. Customer demand drives our business. For example, to address near term needs, we offer critical specification variations, such as special operating ranges or wire bond options on currently available products, while we also design new families of products to meet their emerging long term needs. As a consequence, our portfolio not only includes the widest selection of catalog parts available, it also includes an extensive list of custom, customer-specific products. This degree of responsiveness enables us to provide our OEM customers with the exact products required for their applications.

Preemptive Service.    Our extensive open libraries of design support tools as well as our ability to deliver the specific device required for system prototyping with very short notice enables networking and telecommunication OEMs to design and introduce differentiated products quickly as well as to reduce their development costs. Our open model libraries give designers access 24 hours a day, seven days a week to electrical and behavioral simulation models. Behavioral models are offered in both Verilog and very high speed integrated circuits hardware description language ("VHDL") format to better fit different customers' simulation environments, further streamlining the customers' development process. We currently offer our FPGA controller IP free of charge for use with our Type II+ and Type IIIe SigmaQuad and SigmaDDR Fast SRAM devices, to help enable our customers to design FPGA-based systems quickly and efficiently, and reach the market with their products faster, and are also developing new FPGA controller IP for use with our next generation Type IVe SigmaQuad and SigmaDDR SRAMs, as well as for our next

---

 

generation LLDRAMs.  Controller IP is also available for our Bandwidth Engine products. Our open model libraries and support tools, coupled with the FPGA controller IP, can save our customers months of design effort and leverage the extensive evaluation and timing already performed by our engineers to enhance their products’ performance, reduce development costs and shorten time-to-market.  We refer to this customer support as “Preemptive Service.”

Quality and Reliability.    Networking and telecommunications equipment typically have long product lives, and the cost to repair or replace this equipment due to product failure at any time is prohibitively expensive. The high-quality and reliability of memory products incorporated in our OEM customers' products is, thus, critical. Every product family we offer is subjected to extensive long term reliability testing before receiving qualification certification, and every device shipped is first subjected to burn-in and then to final tests in which the device is operated beyond its specified operating voltage and temperature ranges.

The GSI Strategy

Our objective is to profitably increase our market share in the high performance memory market. Our strategy includes the following key elements:

Continue to Focus on the Networking and Telecommunications Markets.    We intend to continue to focus on designing and developing high transaction rate, low latency, high bandwidth and feature-rich memory products targeted primarily at the networking and telecommunications markets. Increasing network complexity due to higher traffic volume and more advanced traffic content continues to drive OEMs' demand for high-performance networking memory. We believe our active high-performance memory product development and manufacturing expertise coupled with established strategic partnerships will continue to enable us to provide networking and telecommunications OEMs with the early access to next generation Very Fast SRAMs, Low Latency DRAMS, and Bandwidth Engine products that offer superior performance, advanced feature sets and continued high reliability, which they need to design and develop new products that support increasingly complex traffic content and to bring networking and telecommunications equipment to market quickly.

Strengthen and Expand Customer Relationships.    We are focused on maintaining close relationships with industry leaders to facilitate rapid adoption of our products and to enhance our position as a leading provider of high-performance memory. We work with both our customers and with their non-memory IC suppliers that require high-performance memory support. We will continue to work with both groups at the pre-design and design stage of their projects in order to anticipate their future high-performance memory needs and to identify and respond to their immediate requests for currently available products and variants on currently available products. We plan to enhance our relationships with these leading OEMs and IC vendors and to develop similar relationships with additional OEMs and IC vendors.

Continue to Invest in Research and Development to Extend Our Technology Leadership.    We believe we have established a position as a technology leader in the design and development of Very Fast SRAMs. Our Very Fast SRAM products most often provide the highest speed available at a given density for a given device configuration. We intend to maintain and advance our technology leadership through continual enhancement of our existing Very Fast SRAM products, particularly our SigmaQuad/SigmaDDR family of low latency, high-bandwidth synchronous SRAMs, while we continue to broaden our product line with the introduction of other new high performance memory technologies targeted to address the evolving needs of the high performance memory market.

Exploit Opportunities to Expand our Markets.    While we develop our high-performance memory products specifically for the networking and telecommunications markets, they are often applicable across a wide range of industries and applications. We have experienced growth in product sales for military, industrial, test and

---

 

measurement, and medical markets and intend to continue penetrating these and other new markets with similar needs for high-performance memory technologies. We intend to supplement our internal development activities by seeking opportunities to acquire other businesses, product lines or technologies, or enter into strategic partnerships, that would complement our current product lines, expand the breadth of our markets, enhance our technical capabilities, or otherwise provide growth opportunities.

Collaborate with Wafer Foundries to Leverage Leading-edge Process Technologies.    We will continue to rely upon advanced complementary metal oxide semiconductor, or CMOS, technologies, the most commonly used process technologies for manufacturing semiconductor devices, from TSMC for SRAM-based products and from Powerchip for DRAM-based products.  We provide our technology partners with the sort of in-depth feedback for yield and performance improvement that can best come from very large array structures like those found in our products. Our most advanced products currently in production were designed using 40 nanometer process technology on 300 millimeter wafers.

 

Products

We design, develop and market a broad range of high-performance memory products primarily for the networking and telecommunications markets. We specialize in high performance memory products featuring very high transaction rates, high density, low latency, high bandwidth, fast clock access times and low power consumption. We commit to offering our products for longer periods of time than our competitors, typically seven years or more following their initial introduction. Accordingly, we continue to offer products in a variety of package types that have been discontinued by other suppliers.

We currently offer more than 30 families of SRAMs, two families of LLDRAMs, and one family of Bandwidth Engine products. These basic product configurations are the basis for over 15,000 individual products that incorporate a variety of performance specifications and optional features. Our products can be found in a wide range of networking and telecommunications equipment, including core routers, multi-service access routers, universal gateways, enterprise edge routers, service provider edge routers, optical edge routers, fast Ethernet switches and wireless base stations. We also sell our products to OEMs that manufacture products for military applications such as radar and guidance systems, for professional audio applications such as sound mixing systems, for test and measurement applications such as high-speed testers, for automotive applications such as smart cruise control, and for medical applications such as ultrasound and CAT scan equipment.

Synchronous SRAM Products

Synchronous SRAMs are controlled by timing signals, referred to as clocks, which make them easier to use than older style asynchronous SRAMs with similar latency characteristics in applications requiring high bandwidth data transfers. Synchronous SRAMs that employ double data rate interface protocols can transfer data at much higher bandwidth than both single data rate and asynchronous SRAMs.  We currently supply synchronous SRAMs that can cycle at operating frequencies as high as 725 MHz, and we expect to introduce products with operating frequencies of up to 1,333 MHz later in 2015.

BurstRAM™ and NBT™ SRAMs.    We currently offer BurstRAMs and No Bus Turnaround, or NBT, SRAMs that implement a single data rate bus protocol. BurstRAMs were originally developed for microprocessor cache applications and have become the most widely used synchronous SRAMs on the market. They are used in applications where large amounts of data are read or written in single sessions, or bursts. NBT SRAMs are a variation on the BurstRAM theme and were developed to address the needs of moderate performance networking

---

 

applications. NBT SRAMs feature a single data rate bus protocol designed to minimize or eliminate wasted data transfer time slots on the bus when BurstRAMs switch from read to write operations. Both families of products can perform burst data transfers or single cycle transfers at the discretion of the user.

Our BurstRAMs and NBT SRAMs are offered in both pipeline and flow-through modes. Flow-through SRAMs allow the shortest latency. Pipelined SRAMs break the access into discrete clock-controlled steps, allowing new access commands to be accepted while an access is already in progress. Therefore, while flow-through SRAMs offer lower latency, pipelined SRAMs offer greater data bandwidth. Our BurstRAM and NBT SRAM products incorporate a number of features that reduce our OEM customers' cost of ownership and increase their design flexibility, including a JTAG test port and our FLXDrive feature, which allows system designers to optimize signal integrity for a given application.

We currently offer BurstRAMs and NBT SRAMs with storage densities of up to 144 megabits with clock frequency of up to 333 MHz and clock access times as fast as 2 nanoseconds that operate at 3.3, 2.5 or 1.8 volts.

SigmaQuad and SigmaDDR Products.    High-performance double data rate and quad data rate synchronous SRAMs have become the de facto standard for the networking and telecommunications industry. We offer a full line of quad data rate separate I/O SRAMs, known as our SigmaQuad family, as well as a companion line of double data rate common I/O SRAMs, known as our SigmaDDR family.  SigmaQuad SRAMs feature two uni-directional (one input and one output) double data rate data ports (two data ports times double data rate transfers equals quad data rate), controlled via a single address and control port. SigmaDDR SRAMs feature a single bi-directional double data rate data port. We currently offer our SigmaQuad and SigmaDDR devices in multiple bus protocol versions and data burst lengths, and with various power supply and interface voltages, all under the names SigmaQuad, SigmaQuad-II and SigmaQuad-IIIe, and (coming soon) SigmaQuad-IVe, and their SigmaDDR equivalents. We expect to introduce our SigmaQuad-IVe product line later in 2015. An additional variant in this family of SRAMs is the SigmaSIO DDR, which is designed to address some segments of the market currently served by dual-port SRAMs.

We currently offer SigmaQuad/SigmaDDR products in five storage densities, 18 megabits, 36 megabits, 72 megabits, 144 megabits and 288 megabits. These SRAMs are capable of speeds up to 725 MHz (and ,with the introduction of SigmaQuad-IVe, up to 1,333 MHz), and operate on main power supply voltages that range from 2.5 volts to 1.2 volts and interface voltages that range from 1.8 volts to 1.2 volts.

SigmaRAM™ Products.    We offer a family of high-performance, low voltage, synchronous SigmaRAM™ SRAM products designed for use in networking and telecommunications systems.  Our SigmaRAM products include the full range of common I/O SRAM functionality, including late write and double late write protocols, pipelined read cycles, burst data transfers and double data rate read and write data transfers.  We currently offer SigmaRAM products with storage density of 18 megabits, speeds of up to 350 MHz and clock access times as fast as 1.7 nanoseconds that operate at 1.8 volts.

Asynchronous SRAM Products

Unlike synchronous SRAMs, asynchronous SRAMs employ a clock-free control interface. They are widely used in support of high-end digital signal processors, or DSPs. We believe we have one of the broadest portfolios of 3.3 volt, high-speed asynchronous SRAMs. These products are designed to meet the stringent power and performance requirements of networking and telecommunications applications, such as VoIP, cellular base stations, DSL line cards and modems.

---

 

We currently offer asynchronous SRAM products with a variety of storage densities between 1 megabit and 8 megabits and random access times ranging from 7 nanoseconds to 15 nanoseconds. All of our asynchronous SRAMs operate at 3.3 volts.

Low Latency DRAM Products

Our low latency DRAM family fills an under-served market segment between commodity DRAMs and Fast SRAMs. Offering moderate density, moderate speed and moderate cost, LLDRAM technology gives system designers a middle choice when commodity DRAM performance is insufficient but Fast SRAM performance is unnecessary. LLDRAMs offer one-third the latency of commodity DRAMs and four times the density of Fast SRAMs, giving networking equipment designers another tool for solving difficult data management problems.

Our current LLDRAM portfolio includes both 288 megabit and 576 megabit devices that are capable of speeds of up to 533 MHz, and that operate on a 1.8 volt power supply and support both 1.8 volt and 1.5 volt interfaces. They are available in five distinct configurations including common I/O and separate I/O types and data bus widths of x36, x18 and x9. These devices serve as an alternate source for users of a popular, functionally equivalent device from a competing vendor. We plan to expand our LLDRAM portfolio later in 2015 with the introduction of 1.25 Gigabit devices capable of speeds of up to 800 MHz, that operate on a 1.5 volt power supply and support 1.2 volt and 1.0 volt interfaces, and that will be available in common I/O configurations with data bus widths of x36 and x18.

Bandwidth Engine Products

The serial I/O interface and high transaction rate and data bandwidth capability of our Bandwidth Engine products, along with their ability to perform atomic read-modify-write operations, provide a level of performance well-suited for the next generation of high-speed networking systems.

The Bandwidth Engine products are 576 megabit devices that support SerDes speeds of up to 15 Gb/s per transceiver. They are capable of performing in excess of 4 billion transactions per second, and can achieve sustained data bandwidth of up to 400 Gb/s (200 Gb/s input, 200 Gb/s output) and can support four different SerDes lane configurations.

Customers

Our primary sales and marketing strategy is to achieve design wins with leading OEM’s in the networking and telecommunications markets and the other markets we serve. The following is a representative list of our OEM customers that directly or indirectly purchased more than $600,000 of our products in the fiscal year ended March 31, 2015:

 

Many of our OEM customers use contract manufacturers to assemble their equipment. Accordingly, a significant percentage of our net revenues is derived from sales to these contract manufacturers and to consignment warehouses who purchase products from us for use by contract manufacturers. In addition, we sell our products to OEM customers indirectly through domestic and international distributors.

---

 

In the case of sales of our products to distributors and consignment warehouses, the decision to purchase our products is typically made by the OEM customers. In the case of contract manufacturers, OEM customers typically provide a list of approved products to the contract manufacturer, which then has discretion whether or not to purchase our products from that list.

Direct sales to contract manufacturers and consignment warehouses accounted for 33.1%, 37.5% and 42.0% of our net revenues for fiscal 2015,  2014 and 2013, respectively. Sales to foreign and domestic distributors accounted for 58.7%, 50.0% and 47.6% of our net revenues for fiscal 2015,  2014 and 2013, respectively.

The following direct customers accounted for 10% or more of our net revenues in one or more of the following periods:

 

 

Alcatel-Lucent was our largest customer in fiscal 2015 and 2014.  Alcatel-Lucent purchases products directly from us and through contract manufacturers and distributors.  Based on information provided to us by Alcatel-Lucent’s contract manufacturers and our distributors, purchases by Alcatel-Lucent represented approximately 25%, 19% and 12% of our net revenues in fiscal 2015,  2014 and 2013, respectively. Cisco Systems, historically our largest OEM customer, purchases our products primarily through its consignment warehouses, and also purchases some products through its contract manufacturers and directly from us. Based on information provided to us by Cisco Systems' consignment warehouses and contract manufacturers, purchases by Cisco Systems represented approximately 13%, 19% and 29% of our net revenues in fiscal 2015,  2014 and 2013, respectively.  To our knowledge, none of our other OEM customers accounted for more than 10% of our net revenues in any of these periods.

Sales, Marketing and Technical Support

We sell our products primarily through our worldwide network of independent sales representatives and distributors. As of March 31, 2015, we employed 18 sales and marketing personnel, and were supported by over 200 independent sales representatives. We believe that our relationship with our U.S. distributor, Avnet, puts us in a strong position to address the Very Fast SRAM and LLDRAM memory markets in the United States. We currently have regional sales offices located in Canada, China, Hong Kong, Israel and the United States. We believe this international coverage allows us to better serve our distributors and OEM customers by providing them with coordinated support. We believe that our customers' purchasing decisions are based primarily on product performance, availability, features, quality, reliability, price, manufacturing flexibility and service. Many of our OEM customers have had long-term relationships with us based on our success in meeting these criteria.

Our sales are generally made pursuant to purchase orders received between one and six months prior to the scheduled delivery date. Because industry practice allows customers to reschedule or cancel orders on relatively

---

 

short notice, these orders are not firm and hence we believe that backlog is not a good indicator of our future sales. We typically provide a warranty of up to 36 months on our products. Liability for a stated warranty period is usually limited to replacement of defective products.

Our marketing efforts are focused on increasing brand name awareness and providing solutions that address our customers' needs. Key components of our marketing efforts include maintaining an active role in industry standards committees, such as the JEDEC Solid State Technology Association (formerly the Joint Electron Device Engineering Council), or JEDEC, which is responsible for establishing detailed specifications that can be utilized in future system designs. We believe that our participation in and sponsorship of numerous proposals within these committees have increased our profile among leading manufacturers in the networking and telecommunications segment of the Very Fast SRAM market. Our marketing group also provides technical, strategic and tactical sales support to our direct sales personnel, sales representatives and distributors. This support includes in-depth product presentations, datasheets, application notes, simulation models, sales tools, marketing communications, marketing research, trademark administration and other support functions.

We emphasize customer service and technical support in an effort to provide our OEM customers with the knowledge and resources necessary to successfully use our products in their designs. Our customer service organization includes a technical team of applications engineers, technical marketing personnel and, when required, product design engineers. We provide customer support throughout the qualification and sales process and continue providing follow-up service after the sale of our products and on an ongoing basis. In addition, we provide our OEM customers with comprehensive datasheets, application notes and reference designs and access to our FPGA controller IP for use in their product development.

Manufacturing

We outsource our wafer fabrication, assembly and wafer sort testing, which enables us to focus on our design strengths, minimize fixed costs and capital expenditures and gain access to advanced manufacturing technologies. Our engineers work closely with our outsource partners to increase yields, reduce manufacturing costs, and help assure the quality of our products.

Currently, all of our wafers are manufactured by TSMC and Powerchip under individually negotiated purchase orders. We do not currently have a long-term supply contract with either of these foundries, and, therefore, neither of them is obligated to manufacture products for us for any specified period, in any specified quantity or at any specified price, except as may be provided in a particular purchase order. Our future success depends in part on our ability to secure sufficient capacity at TSMC, Powerchip or other independent foundries to supply us with the wafers we require.

Our newest, leading edge SRAM and Bandwidth Engine products are manufactured using 40 nanometer process technology at TSMC. The majority of our current SRAM products are manufactured using 0.13 micron, 90 nanometer and 65 nanometer process technologies on 300 millimeter wafers at TSMC. Our LLDRAM production at Powerchip uses 72 nanometer and 63 nanometer process technologies.  On-going development programs are underway to extend, expand and/or cost reduce most our product families.

Our master die methodology enables multiple product families, and variations thereof, to be manufactured from a single mask set. As a result, based upon the way available die from a wafer are metalized, wire bonded, packaged and tested, we can create a number of different products. The manufacturing process consists of two phases, the first of which takes approximately eight to twelve weeks and results in wafers that have the potential to yield multiple products within a given product family. After the completion of this phase, the wafers are stored pending customer orders. Once we receive orders for a particular product, we perform the second phase, consisting

---

 

of final wafer processing, assembly, burn-in and test, which takes approximately four to eight weeks to complete. This two-step manufacturing process enables us to significantly shorten our product lead times, providing flexibility for customization and to increase the availability of our products.

All of our manufactured wafers are tested for electrical compliance and most are packaged at Advanced Semiconductor Engineering, or ASE, which is located in Taiwan. Our test procedures require that all of our products be subjected to accelerated burn-in and extensive functional electrical testing which is performed at our Taiwan and U.S. test facilities.

Research and Development

Research and development expenses were $11.9 million in fiscal 2015,  $13.1 million in fiscal 2014 and $11.5 million in fiscal 2013. Our research and development staff includes engineering professionals with extensive experience in the areas of SRAM design, DRAM design and systems level networking and telecommunications equipment design. The design process for our products is complex. As a result, we have made substantial investments in computer-aided design and engineering resources to manage our design process. Our current development focus is on the SigmaQuad SRAM family and our family of LLDRAM products.

Competition

Our existing competitors include many large domestic and international companies, some of which have substantially greater resources, offer other types of memory and/or non-memory technologies and may have longer standing relationships with OEM customers than we do. Unlike us, some of our principal competitors maintain their own semiconductor fabs, which may, at times, provide them with capacity, cost and technical advantages.

Our principal competitors include Cypress Semiconductor, Integrated Silicon Solution, Micron and REC. While some of our competitors offer a broad array of memory products and offer some of their products at lower prices than we do, we believe that our focus on, and performance leadership in, low latency, high density Very Fast SRAMs provide us with key competitive advantages.

We believe that our ability to compete successfully in the rapidly evolving markets for memory products for the networking and telecommunications markets depends on a number of factors, including:

We believe we compete favorably with our competitors based on these factors. However, we may not be able to compete successfully in the future with respect to any of these factors. Our failure to compete successfully in these or other areas could harm our business.

The market for networking memory products is competitive and is characterized by technological change, declining average selling prices and product obsolescence. Competition could increase in the future from existing competitors and from other companies that may enter our existing or future markets with solutions that may be less

---

 

costly or provide higher performance or more desirable features than our products. This increased competition may result in price reductions, reduced profit margins and loss of market share.

In addition, we are vulnerable to advances in technology by competitors, including new SRAM architectures as well as new forms of DRAM and other new memory technologies. Because we have limited experience developing IC products other than Very Fast SRAMs and LLDRAMs, any efforts by us to introduce new products based on a new memory technology may not be successful and, as a result, our business may suffer.

Intellectual Property

Our ability to compete successfully depends, in part, upon our ability to protect our proprietary technology and information. We rely on a combination of patents, copyrights, trademarks, trade secret laws, non-disclosure and other contractual arrangements and technical measures to protect our intellectual property. We currently hold 23 United States patents and have 12 patent applications pending. We do not consider our existing patents to be materially important to our business, and we cannot assure you that any patents will be issued as a result of our pending applications or that any patents issued will be valuable to our business. We believe that factors such as the technological and creative skills of our personnel and the success of our ongoing product development efforts are more important than our patent portfolio in maintaining our competitive position. We generally enter into confidentiality or license agreements with our employees, distributors, customers and potential customers and limit access to our proprietary information. Our intellectual property rights, if challenged, may not be upheld as valid, may not be adequate to prevent misappropriation of our technology or may not prevent the development of competitive products. Additionally, we may not be able to obtain patents or other intellectual property protection in the future. Furthermore, the laws of certain foreign countries in which our products are or may be developed, manufactured or sold, including various countries in Asia, may not protect our products or intellectual property rights to the same extent as do the laws of the United States and thus make the possibility of piracy of our technology and products more likely in these countries.

The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights, which have resulted in significant and often protracted and expensive litigation. We or our foundry from time to time are notified of claims that we may be infringing patents or other intellectual property rights owned by third parties. We have recently been involved in patent infringement litigation.  See Item 3. Legal Proceedings.  We have been subject to other intellectual property claims in the past and we may be subject to additional claims and litigation in the future. Litigation by or against us relating to allegations of patent infringement or other intellectual property matters could result in significant expense to us and divert the efforts of our technical and management personnel, whether or not such litigation results in a determination favorable to us. In the event of an adverse result in any such litigation, we could be required to pay substantial damages, cease the manufacture, use and sale of infringing products, expend significant resources to develop non-infringing technology, discontinue the use of certain processes or obtain licenses to the infringing technology. Licenses may not be offered or the terms of any offered licenses may not be acceptable to us. If we fail to obtain a license from a third party for technology used by us, we could incur substantial liabilities and be required to suspend the manufacture of products or the use by our foundry of certain processes.

Employees

As of March 31, 2015, we had 138 full-time employees, including 74 engineers, of which 43 are engaged in research and development and 37 have PhD or MS degrees, 18 employees in sales and marketing, ten employees in general and administrative capacities and 68 employees in manufacturing. Of these employees, 57 are based in our Sunnyvale facility and 60 are based in our Taiwan facility. We believe that our future success will depend in large part on our ability to attract and retain highly-skilled, engineering, managerial, sales and marketing personnel. Our

---

 

employees are not represented by any collective bargaining unit, and we have never experienced a work stoppage. We believe that our employee relations are good.

Item 1A.    Risk Factors

 

        Our future performance is subject to a variety of risks. If any of the following risks actually occur, our business, financial condition and results of operations could suffer and the trading price of our common stock could decline. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations. You should also refer to other information contained in this report, including our consolidated financial statements and related notes.

Unpredictable fluctuations in our operating results could cause our stock price to decline.

Our quarterly and annual revenues, expenses and operating results have varied significantly and are likely to vary in the future. For example, in the twelve fiscal quarters ended March 31, 2015, we recorded net revenues of as much as $17.5 million and as little as $12.8 million and quarterly operating income of as much as $1.5 million and, in seven quarters, operating losses, including the operating loss of $3.6 million in the quarter ended March 31, 2014. We therefore believe that period-to-period comparisons of our operating results are not a good indication of our future performance, and you should not rely on them to predict our future performance or the future performance of our stock price. In future periods, we may not have any revenue growth, or our revenues could decline. Furthermore, if our operating expenses exceed our expectations, our financial performance could be adversely affected. Factors that may affect periodic operating results in the future include:

---

 

Our expenses are, to a large extent, fixed, and we expect that these expenses will increase in the future. We will not be able to adjust our spending quickly if our revenues fall short of our expectations. If this were to occur, our operating results would be harmed. If our operating results in future quarters fall below the expectations of market analysts and investors, the price of our common stock could fall.

Our two largest OEM customers account for a significant percentage of our net revenues. If either of these customers, or any of our other major customers, reduces the amount they purchase or stop purchasing our products, our operating results will suffer.

Alcatel-Lucent, currently our largest customer, purchases our products directly from us and through contract manufacturers and distributors.  Purchases by Alcatel-Lucent represented approximately 25%, 19% and 12% of our net revenues in fiscal 2015, 2014 and 2013, respectively. Cisco Systems, historically our largest OEM customer, purchases our products through its consignment warehouses and contract manufacturers and directly from us. Purchases by Cisco Systems represented approximately 13%, 19% and 29% of our net revenues in fiscal 2015,  2014 and 2013, respectively. We expect that our operating results in any given period will continue to depend significantly on orders from our key OEM customers, particularly Alcatel-Lucent and Cisco Systems, and our future success is dependent to a large degree on the business success of these OEMs over which we have no control. We do not have long-term contracts with Alcatel-Lucent, Cisco Systems or any of our other major OEM customers, distributors or contract manufacturers that obligate them to purchase our products.  We expect that future direct and indirect sales to Alcatel-Lucent and Cisco Systems will continue to fluctuate significantly on a quarterly basis and that such fluctuations may substantially affect our operating results in future periods. If we fail to continue to sell to our key OEM customers, distributors or contract manufacturers in sufficient quantities, our business could be harmed.

We have incurred significant losses in prior periods and may incur losses in the future.

We have incurred significant losses in prior periods. We incurred losses of $5.0 million and $6.2 million during fiscal 2015 and 2014, respectively. Although we have operated profitably during nine of our last eleven fiscal years, there can be no assurance that our Very Fast SRAMs will continue to receive broad market acceptance or that we will be able to achieve sustained revenue growth. Our failure to do so may result in additional losses in the future. In addition, our operating expenses over the past several years have included substantial litigation-related expenses, and we expect that these expenses will continue to be substantial over the next several quarters.  Our expenses will also increase if we are able to expand our business. If our revenues do not grow to offset these expected expenses, our business will suffer.

---

 

We depend upon the sale of our Very Fast SRAMs for most of our revenues, and a downturn in demand for these products could significantly reduce our revenues and harm our business.

We derive most of our revenues from the sale of Very Fast SRAMs, and we expect that sales of these products will represent the substantial majority of our revenues for the foreseeable future. Our business depends in large part upon continued demand for our products in the markets we currently serve, and adoption of our products in new markets. Market adoption will be dependent upon our ability to increase customer awareness of the benefits of our products and to prove their high-performance and cost-effectiveness. We may not be able to sustain or increase our revenues from sales of our products, particularly if the networking and telecommunications markets were to experience another significant downturn in the future. Any decrease in revenues from sales of our products could harm our business more than it would if we offered a more diversified line of products.

If we do not successfully develop new products to respond to rapid market changes due to changing technology and evolving industry standards, particularly in the networking and telecommunications markets, our business will be harmed.

If we fail to offer technologically advanced products and respond to technological advances and emerging standards, we may not generate sufficient revenues to offset our development costs and other expenses, which will hurt our business. The development of new or enhanced products is a complex and uncertain process that requires the accurate anticipation of technological and market trends. In particular, the networking and telecommunications markets are rapidly evolving and new standards are emerging. We are vulnerable to advances in technology by competitors, including new SRAM architectures, new forms of DRAM and the emergence of new memory technologies that could enable the development of products that feature higher performance or lower cost. We may experience development, marketing and other technological difficulties that may delay or limit our ability to respond to technological changes, evolving industry standards, competitive developments or end-user requirements. For example, because we have limited experience developing integrated circuits, or IC, products other than Very Fast SRAMs, our efforts to introduce new products may not be successful and our business may suffer. Other challenges that we face include:

---

 

We are subject to the highly cyclical nature of the networking and telecommunications markets.

Our products are incorporated into routers, switches, wireless local area network infrastructure equipment, wireless base stations and network access equipment used in the highly cyclical networking and telecommunications markets. We expect that the networking and telecommunications markets will continue to be highly cyclical, characterized by periods of rapid growth and contraction. Our business and our operating results are likely to fluctuate, perhaps quite severely, as a result of this cyclicality.

The market for Very Fast SRAMs is highly competitive.

The market for Very Fast SRAMs, which are used primarily in networking and telecommunications equipment, is characterized by price erosion, rapid technological change, cyclical market patterns and intense foreign and domestic competition. Several of our competitors offer a broad array of memory products and have greater financial, technical, marketing, distribution and other resources than we have. Some of our competitors maintain their own semiconductor fabrication facilities, which may provide them with capacity, cost and technical advantages over us. We cannot assure you that we will be able to compete successfully against any of these competitors. Our ability to compete successfully in this market depends on factors both within and outside of our control, including:

In addition, we are vulnerable to advances in technology by competitors, including new SRAM architectures and new forms of DRAM, or the emergence of new memory technologies that could enable the development of products that feature higher performance, lower cost or lower power capabilities. Additionally, the trend toward incorporating SRAM into other chips in the networking and telecommunications markets has the potential to reduce future demand for Very Fast SRAM products. There can be no assurance that we will be able to compete successfully in the future. Our failure to compete successfully in these or other areas could harm our business. 

The average selling prices of our products are expected to decline, and if we are unable to offset these declines, our operating results will suffer.

Historically, the average unit selling prices of our products have declined substantially over the lives of the products, and we expect this trend to continue. A reduction in overall average selling prices of our products could result in reduced revenues and lower gross margins. Our ability to increase our net revenues and maintain our gross margins despite a decline in the average selling prices of our products will depend on a variety of factors, including our ability to introduce lower cost versions of our existing products, increase unit sales volumes of these products, and introduce new products with higher prices and greater margins. If we fail to accomplish any of these objectives, our business will suffer. To reduce our costs, we may be required to implement design changes that lower our manufacturing costs, negotiate reduced purchase prices from our independent foundries and our independent assembly and test vendors, and successfully manage our manufacturing and subcontractor relationships. Because we

---

 

do not operate our own wafer foundry or assembly facilities, we may not be able to reduce our costs as rapidly as companies that operate their own foundries or facilities.

Global economic and market conditions may adversely affect our business, financial condition and results of operations.

We sell our products to end customers both in the United States and internationally.  We also rely heavily on our suppliers in Asia.  We are therefore susceptible to adverse domestic and international economic and market conditions.  In recent years, turmoil in global financial markets and economic conditions has impacted credit availability, consumer spending and capital expenditures, including expenditures for networking and telecommunications equipment.  Weakness in global networking and telecommunications markets, particularly in Asia, has continued to adversely impact our revenues in recent quarters.  Slowness in economic growth, domestically and in our key markets, uncertainty regarding macroeconomic trends, and volatility in financial markets may continue to adversely affect our business, financial condition and results of operations over coming quarters.

We are dependent on a number of single source suppliers, and if we fail to obtain adequate supplies, our business will be harmed and our prospects for growth will be curtailed.

We currently purchase several key components used in the manufacture of our products from single sources and are dependent upon supply from these sources to meet our needs. If any of these suppliers cannot provide components on a timely basis, at the same price or at all, our ability to manufacture our products will be constrained and our business will suffer. Most significantly, we obtain wafers for our Very Fast SRAM products from a single foundry, TSMC, and most of them are packaged at ASE. Wafers for our LLDRAM products are obtained exclusively from Powerchip.  If we are unable to obtain an adequate supply of wafers from TSMC or Powerchip or find alternative sources in a timely manner, we will be unable to fulfill our customer orders and our operating results will be harmed. We do not have supply agreements with TSMC, Powerchip, ASE or any of our other independent assembly and test suppliers, and instead obtain manufacturing services and products from these suppliers on a purchase-order basis. Our suppliers, including TSMC and Powerchip, have no obligation to supply products or services to us for any specific product, in any specific quantity, at any specific price or for any specific time period. As a result, the loss or failure to perform by any of these suppliers could adversely affect our business and operating results.

Should any of our single source suppliers experience manufacturing failures or yield shortfalls, be disrupted by natural disaster or political instability, choose to prioritize capacity or inventory for other uses or reduce or eliminate deliveries to us for any other reason, we likely will not be able to enforce fulfillment of any delivery commitments and we would have to identify and qualify acceptable replacements from alternative sources of supply. In particular, if TSMC is unable to supply us with sufficient quantities of wafers to meet all of our requirements, we would have to allocate our products among our customers, which would constrain our growth and might cause some of them to seek alternative sources of supply. Since the manufacturing of wafers and other components is extremely complex, the process of qualifying new foundries and suppliers is a lengthy process and there is no assurance that we would be able to find and qualify another supplier without materially adversely affecting our business, financial condition and results of operations

Because we outsource our wafer manufacturing and independent wafer foundry capacity is limited, we may be required to enter into costly long-term supply arrangements to secure foundry capacity.

We do not have long-term supply agreements with TSMC or Powerchip, but instead obtain our wafers on a purchase order basis. In order to secure future wafer supply from TSMC or Powerchip or from other independent foundries, we may be required to enter into various arrangements with them, which could include:

---

 

We may not be able to make any of these arrangements in a timely fashion or at all, and these arrangements, if any, may not be on terms favorable to us. Moreover, even if we are able to secure independent foundry capacity, we may be obligated to use all of that capacity or incur penalties. These penalties may be expensive and could harm our financial results.

If we are unable to offset increased wafer fabrication costs by increasing the average selling prices of our products, our gross margins will suffer.

If there is a significant upturn in the networking and telecommunications markets that results in increased demand for our products and competing products, the available supply of wafers may be limited. As a result, we could be required to obtain additional manufacturing capacity in order to meet increased demand. Securing additional manufacturing capacity may cause our wafer fabrication costs to increase. If we are unable to offset these increased costs by increasing the average selling prices of our products, our gross margins will decline.

We rely heavily on distributors and our success depends on our ability to develop and manage our indirect distribution channels.

A significant percentage of our sales are made to distributors and to contract manufacturers who incorporate our products into end products for OEMs. For example, in fiscal 2015,  2014 and 2013, our distributor Avnet Logistics accounted for 35.2%, 30.3% and 26.5%, respectively, of our net revenues. Avnet Logistics and our other existing distributors may choose to devote greater resources to marketing and supporting the products of other companies. Since we sell through multiple channels and distribution networks, we may have to resolve potential conflicts between these channels. For example, these conflicts may result from the different discount levels offered by multiple channel distributors to their customers or, potentially, from our direct sales force targeting the same equipment manufacturer accounts as our indirect channel distributors. These conflicts may harm our business or reputation.

We may be unable to accurately predict future sales through our distributors, which could harm our ability to efficiently manage our resources to match market demand.

Our financial results, quarterly product sales, trends and comparisons are affected by fluctuations in the buying patterns of the OEMs that purchase our products from our distributors. While we attempt to assist our distributors in maintaining targeted stocking levels of our products, we may not consistently be accurate or successful. This process involves the exercise of judgment and use of assumptions as to future uncertainties, including end user demand. Inventory levels of our products held by our distributors may exceed or fall below the levels we consider desirable on a going-forward basis. This could result in distributors returning unsold inventory to us, or in us not having sufficient inventory to meet the demand for our products. If we are not able to accurately predict sales through our distributors or effectively manage our relationships with our distributors, our business and financial results will suffer.

---

 

A small number of customers generally account for a significant portion of our accounts receivable in any period, and if any one of them fails to pay us, our financial position and operating results will suffer.

At March 31, 2015,  four customers accounted for 25%, 20%, 16% and 13% of our accounts receivable, respectively. If any of these customers do not pay us, our financial position and operating results will be harmed. Generally, we do not require collateral from our customers.

We have previously disclosed a material weakness in our internal control over financial reporting relating to the evaluation and calculation of our inventory reserve which management believes has been fully remediated. Should we have inadequately remediated this material weakness or should we otherwise fail to maintain effective internal control over financial reporting and disclosure controls and processes, our ability to report our financial condition and results of operations accurately and on a timely basis could be adversely affected.

In connection with the completion of the quarter-end closing and review procedures for the quarter ended December 31, 2013, certain errors were identified in the evaluation and calculation of our inventory write-down for the quarter and nine month period then ended that were the result of a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

During these closing and review procedures, our management determined that we had not designed and maintained effective controls over the review of supporting information to confirm the completeness and accuracy of our calculations for the write-down of excess or obsolete inventory, thereby affecting the valuation of our inventory as of December 31, 2013.  While this control deficiency did not result in any material misstatement of our historical financial statements, it did result in adjustments identified by our auditors as part of their quarterly review process, and require corrections after our initial estimate of excess and obsolete inventory write-downs for the three month period ended December 31, 2013.

A material weakness in our internal control over financial reporting could adversely impact our ability to provide timely and accurate financial information.  Following the identification of the error in our third quarter financial statements and the material weakness that gave rise to the error, our management implemented a remediation plan which it believes fully remediated the material weakness.  Should our remediation efforts prove to have been inadequate or should we otherwise fail to maintain effective internal control over financial reporting and disclosure controls and procedures, we could be unable to meet our reporting obligations accurately and on a timely basis. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could adversely affect the trading price of our common stock.

Our acquisition of companies or technologies could prove difficult to integrate, disrupt our business, dilute stockholder value and adversely affect our operating results.

In August 2009, we consummated the acquisition of substantially all of the assets related to the SRAM memory device product line of Sony Corporation. We intend to supplement our internal development activities by seeking opportunities to make additional acquisitions or investments in companies, assets or technologies that we believe are complementary or strategic. Other than the Sony acquisition, we have not made any such acquisitions or investments, and therefore our experience as an organization in making such acquisitions and investments is limited. In connection with future acquisitions or investments we may make, we face numerous risks, including:

---

 

If we proceed with additional acquisitions or investments, we may be required to use a considerable amount of our cash, or to finance the transaction through debt or equity securities offerings, which may decrease our financial liquidity or dilute our stockholders and affect the market price of our stock. As a result, if we fail to properly evaluate and execute acquisitions or investments, our business and prospects may be harmed.

Claims that we infringe third party intellectual property rights could seriously harm our business and require us to incur significant costs.

In recent years, there has been significant litigation in the semiconductor industry involving patents and other intellectual property rights.  We have recently been involved in protracted patent infringement litigation, and  we could become subject to additional claims or litigation in the future as a result of allegations that we infringe others' intellectual property rights or that our use of intellectual property otherwise violates the law. Claims that our products infringe the proprietary rights of others would force us to defend ourselves and possibly our customers, distributors or manufacturers against the alleged infringement. Any such litigation regarding intellectual property could result in substantial costs and diversion of resources and could have a material adverse effect on our business, financial condition and results of operations. Similarly, changing our products or processes to avoid infringing the rights of others may be costly or impractical. If any claims received in the future were to be upheld, the consequences to us could require us to:

Although patent disputes in the semiconductor industry have often been settled through cross-licensing arrangements, we may not be able in any or every instance to settle an alleged patent infringement claim through a cross-licensing arrangement in part because we have a more limited patent portfolio than many of our competitors. If a successful claim is made against us or any of our customers and a license is not made available to us on commercially reasonable terms or we are required to pay substantial damages or awards, our business, financial condition and results of operations would be materially adversely affected.

---

 

Our business will suffer if we are unable to protect our intellectual property.

Our success and ability to compete depends in large part upon protecting our proprietary technology. We rely on a combination of patent, trade secret, copyright and trademark laws and non-disclosure and other contractual agreements to protect our proprietary rights. These agreements and measures may not be sufficient to protect our technology from third-party infringement. Monitoring unauthorized use of our intellectual property is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. Our attempts to enforce our intellectual property rights could be time consuming and costly. We are currently involved in litigation to enforce our intellectual property rights and to protect our trade secrets. Additional litigation of this type may be necessary in the future. Any such litigation could result in substantial costs and diversion of resources. If competitors are able to use our technology without our approval or compensation, our ability to compete effectively could be harmed.

We may experience difficulties in transitioning to smaller geometry process technologies and other more advanced manufacturing process technologies, which may result in reduced manufacturing yields, delays in product deliveries and increased expenses.

In order to remain competitive, we expect to continue to transition the manufacture of our products to smaller geometry process technologies. This transition will require us to migrate to new manufacturing processes for our products and redesign certain products. The manufacture and design of our products is complex, and we may experience difficulty in transitioning to smaller geometry process technologies or new manufacturing processes. These difficulties could result in reduced manufacturing yields, delays in product deliveries and increased expenses. We are dependent on our relationships with TSMC and Powerchip to transition successfully to smaller geometry process technologies and to more advanced manufacturing processes. We cannot assure you that TSMC or Powerchip will be able to effectively manage the transition or that we will be able to maintain our relationship with them. If we or TSMC or Powerchip experience significant delays in this transition or fail to implement these transitions, our business, financial condition and results of operations could be materially and adversely affected.

Manufacturing process technologies are subject to rapid change and require significant expenditures for research and development.

We continuously evaluate the benefits of migrating to smaller geometry process technologies in order to improve performance and reduce costs. Historically, these migrations to new manufacturing processes have resulted in significant initial design and development costs associated with pre-production mask sets for the manufacture of new products with smaller geometry process technologies.   For example, in fiscal 2014, we incurred $809,000 and $648,000, respectively, in research and development expense associated with pre-production mask sets which were not later used in production as part of the transition to our new 40 nanometer SRAM process technology and 63 nanometer DRAM process technology.  We will incur similar expenses in the future as we continue to transition our products to smaller geometry processes. The costs inherent in the transition to new manufacturing process technologies will adversely affect our operating results and our gross margin.

Our products are complex to design and manufacture and could contain defects, which could reduce revenues or result in claims against us.

We develop complex products. Despite testing by us and our OEM customers, design or manufacturing errors may be found in existing or new products. These defects could result in a delay in recognition or loss of revenues, loss of market share or failure to achieve market acceptance. These defects may also cause us to incur significant warranty, support and repair costs, divert the attention of our engineering personnel from our product development

---

 

efforts, result in a loss of market acceptance of our products and harm our relationships with our OEM customers. Our OEM customers could also seek and obtain damages from us for their losses. A product liability claim brought against us, even if unsuccessful, would likely be time consuming and costly to defend.

Defects in wafers and other components used in our products and arising from the manufacturing of these products may not be fully recoverable from TSMC or our other suppliers. For example, in the quarter ended December 31, 2005, we incurred a charge of approximately $900,000 related to the write-off of inventory resulting from an error in the assembly process at one of our suppliers. This write-off adversely affected our operating results for fiscal 2006.

Demand for our products may decrease if our OEM customers experience difficulty manufacturing, marketing or selling their products.

Our products are used as components in our OEM customers' products. For example, Cisco Systems, historically our largest OEM customer, incorporates our products in a number of its networking routers and switches. Accordingly, demand for our products is subject to factors affecting the ability of our OEM customers to successfully introduce and market their products, including:

As a result, if OEM customers reduce their purchases of our products, our business will suffer.

Our products have lengthy sales cycles that make it difficult to plan our expenses and forecast results.

Our products are generally incorporated in our OEM customers' products at the design stage. However, their decisions to use our products often require significant expenditures by us without any assurance of success, and often precede volume sales, if any, by a year or more. If an OEM customer decides at the design stage not to incorporate our products into their products, we will not have another opportunity for a design win with respect to that customer's product for many months or years, if at all. Our sales cycle can take up to 24 months to complete, and because of this lengthy sales cycle, we may experience a delay between increasing expenses for research and development and our sales and marketing efforts and the generation of volume production revenues, if any, from these expenditures. Moreover, the value of any design win will largely depend on the commercial success of our OEM customers' products. There can be no assurance that we will continue to achieve design wins or that any design win will result in future revenues.

---

 

Any significant order cancellations or order deferrals could adversely affect our operating results.

We typically sell products pursuant to purchase orders that customers can generally cancel or defer on short notice without incurring a significant penalty. Any significant cancellations or deferrals in the future could materially and adversely affect our business, financial condition and results of operations. Cancellations or deferrals could cause us to hold excess inventory, which could reduce our profit margins, increase product obsolescence and restrict our ability to fund our operations. We generally recognize revenue upon shipment of products to a customer. If a customer refuses to accept shipped products or does not pay for these products, we could miss future revenue projections or incur significant charges against our income, which could materially and adversely affect our operating results.

If our business grows, such growth may place a significant strain on our management and operations and, as a result, our business may suffer.

We are endeavoring to expand our business, and any growth that we are successful in achieving could place a significant strain on our management systems, infrastructure and other resources. To manage such growth of our operations and resulting increases in the number of our personnel, we will need to invest the necessary capital to continue to improve our operational, financial and management controls and our reporting systems and procedures. Our controls, systems and procedures may prove to be inadequate should we experience significant growth. In addition, we may not have sufficient administrative staff to support our operations. For example, we currently have only five employees in our finance department in the United States, including our Chief Financial Officer. Furthermore, our officers have limited experience in managing large or rapidly growing businesses. If our management fails to respond effectively to changes in our business, our business may suffer.

Our international business exposes us to additional risks.

Products shipped to destinations outside of the United States accounted for 66.2%, 69.2% and 68.8% of our net revenues in fiscal 2015,  2014 and 2013, respectively. Moreover, a substantial portion of our products is manufactured and tested in Taiwan. We intend to continue expanding our international business in the future. Conducting business outside of the United States subjects us to additional risks and challenges, including:

---

 

Moreover, our reporting currency is the U.S. dollar. However, a portion of our cost of revenues and our operating expenses is denominated in currencies other than the U.S. dollar, primarily the New Taiwanese dollar. As a result, appreciation or depreciation of other currencies in relation to the U.S. dollar could result in transaction gains or losses that could impact our operating results. We do not currently engage in currency hedging activities to reduce the risk of financial exposure from fluctuations in foreign exchange rates.

TSMC and Powerchip, as well as our other independent suppliers and many of our OEM customers have operations in the Pacific Rim, an area subject to significant earthquake risk and adverse consequences related to the potential outbreak of contagious diseases such as the H1N1 Flu.

The foundries that manufacture our Fast SRAM and LLDRAM products, TSMC and Powerchip, and all of the principal independent suppliers that assemble and test our products are located in Taiwan. Many of our customers are also located in the Pacific Rim. The risk of an earthquake in these Pacific Rim locations is significant. The occurrence of an earthquake or other natural disaster near the fabrication facilities of TSMC or our other independent suppliers could result in damage, power outages and other disruptions that impair their production and assembly capacity. Any disruption resulting from such events could cause significant delays in the production or shipment of our products until we are able to shift our manufacturing, assembling, packaging or production testing from the affected contractor to another third-party vendor. In such an event, we may not be able to obtain alternate foundry capacity on favorable terms, or at all.

The outbreak of SARS in 2003 curtailed travel to and from certain countries, primarily in the Asia-Pacific region, and limited travel within those countries. If there were to be another outbreak of a contagious disease, such as SARS or the H1N1 Flu, that significantly affected the Asia-Pacific region, the operations of our key suppliers could be disrupted. In addition, our business could be harmed if such an outbreak resulted in travel being restricted, as it was during parts of 2003, or if it adversely affected the operations of our suppliers or our OEM customers or the demand for our products or our OEM customers' products.

Changes in Taiwan's political, social and economic environment may affect our business performance.

Because much of the manufacturing and testing of our products is conducted in Taiwan, our business performance may be affected by changes in Taiwan's political, social and economic environment. For example, any political instability resulting from the relationship among the United States, Taiwan and the People's Republic of China could damage our business. Moreover, the role of the Taiwanese government in the Taiwanese economy is significant. Taiwanese policies toward economic liberalization, and laws and policies affecting technology companies, foreign investment, currency exchange rates, taxes and other matters could change, resulting in greater restrictions on our ability and our suppliers' ability to do business and operate facilities in Taiwan. If any of these changes were to occur, our business could be harmed and our stock price could decline.

We are substantially dependent on the continued services and performance of our senior management and other key personnel.

Our future success is substantially dependent on the continued services and continuing contributions of our senior management who must work together effectively in order to design our products, expand our business, increase our revenues and improve our operating results. Members of our senior management team have long-standing and important relationships with our key customers and suppliers.  The loss of services of Lee-Lean Shu, our President and Chief Executive Officer, Robert Yau, our Vice President of Engineering, any other executive officer or other key employee could significantly delay or prevent the achievement of our development and strategic

---

 

objectives. We do not have employment contracts with, nor maintain key person insurance on, any of our executive officers.

If we are unable to recruit or retain qualified personnel, our business and product development efforts could be harmed.

We must continue to identify, recruit, hire, train, retain and motivate highly skilled technical, managerial, sales and marketing and administrative personnel. Competition for these individuals is intense, and we may not be able to successfully recruit, assimilate or retain sufficiently qualified personnel. We may encounter difficulties in recruiting and retaining a sufficient number of qualified engineers, which could harm our ability to develop new products and adversely impact our relationships with existing and future end-users at a critical stage of development. The failure to recruit and retain necessary technical, managerial, sales, marketing and administrative personnel could harm our business and our ability to obtain new OEM customers and develop new products.

We may need to raise additional capital in the future, which may not be available on favorable terms or at all, and which may cause dilution to existing stockholders.

We may need to seek additional funding in the future. We do not know if we will be able to obtain additional financing on favorable terms, if at all. If we cannot raise funds on acceptable terms, if and when needed, we may not be able to develop or enhance our products, take advantage of future opportunities or respond to competitive pressures or unanticipated requirements, and we may be required to reduce operating costs, which could seriously harm our business. In addition, if we issue equity securities, our stockholders may experience dilution or the new equity securities may have rights, preferences or privileges senior to those of our common stock.

Some of  our products are incorporated into advanced military electronics, and changes in international geopolitical circumstances and domestic budget considerations may hurt our business.

Some of our products are incorporated into advanced military electronics such as radar and guidance systems. Military expenditures and appropriations for such purchases rose significantly in recent years. However, as the current conflict in Afghanistan winds down, demand for our products for use in military applications may decrease,  and our operating results could suffer. Domestic budget considerations may also adversely affect our operating results. For example, if governmental appropriations for military purchases of electronic devices that include our products are reduced, our revenues will likely decline.

Our operations involve the use of hazardous and toxic materials, and we must comply with environmental laws and regulations, which can be expensive, and may affect our business and operating results.

We are subject to federal, state and local regulations relating to the use, handling, storage, disposal and human exposure to hazardous and toxic materials. If we were to violate or become liable under environmental laws in the future as a result of our inability to obtain permits, human error, accident, equipment failure or other causes, we could be subject to fines, costs, or civil or criminal sanctions, face property damage or personal injury claims or be required to incur substantial investigation or remediation costs, which could be material, or experience disruptions in our operations, any of which could have a material adverse effect on our business. In addition, environmental laws could become more stringent over time imposing greater compliance costs and increasing risks and penalties associated with violations, which could harm our business.

We also face increasing complexity in our product design as we adjust to new and future requirements relating to the materials composition of our products, including the restrictions on lead and other hazardous substances applicable to specified electronic products placed on the market in the European Union (Restriction on the Use of

---

 

Hazardous Substances Directive 2002/95/EC, also known as the RoHS Directive). We also expect that our operations will be affected by other new environmental laws and regulations on an ongoing basis. Although we cannot predict the ultimate impact of any such new laws and regulations, they will likely result in additional costs, and could require that we change the design and/or manufacturing of our products, any of which could have a material adverse effect on our business.

The trading price of our common stock is subject to fluctuation and is likely to be volatile.

The trading price of our common stock may fluctuate significantly in response to a number of factors, some of which are beyond our control, including:

In recent years the stock market in general, and the market for technology stocks in particular, have experienced extreme price fluctuations, which have often been unrelated to the operating performance of affected companies. The market price of our common stock might experience significant fluctuations in the future, including fluctuations unrelated to our performance. These fluctuations could materially adversely affect our business relationships, our ability to obtain future financing on favorable terms or otherwise harm our business. In addition, in the past, securities class action litigation has often been brought against a company following periods of volatility in the market price of its securities. This risk is especially acute for us because the extreme volatility of market prices of technology companies has resulted in a larger number of securities class action claims against them. Due to the potential volatility of our stock price, we may in the future be the target of similar litigation. Securities litigation could result in substantial costs and divert management's attention and resources. This could harm our business and cause the value of our stock to decline.

Use of a portion of our cash reserves to repurchase shares of our common stock presents potential risks and disadvantages to us and our continuing stockholders. 

From November 2008 through March 2015 we repurchased and retired an aggregate of 8,728,532 shares of our common stock at a total cost of $46.5 million, including 3,846,153 shares repurchased at a total cost of $25 million pursuant to a modified “Dutch auction” self-tender offer that we completed in August 2014 and additional shares repurchased in the open market pursuant to our stock repurchase program.  At March 31, 2015, we had outstanding authorization from our Board of Directors to purchase up to an additional $8.5 million of our 

---

 

common stock from time to time under our repurchase program.    Although our Board has determined that these repurchases are in the best interests of our stockholders, they expose us to certain risks including: 

Our executive officers, directors and entities affiliated with them hold a substantial percentage of our common stock.

As of May 31, 2015,  our executive officers, directors and entities affiliated with them beneficially owned approximately 31% of our outstanding common stock. As a result, these stockholders will be able to exercise substantial influence over, and may be able to effectively control, matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, which could have the effect of delaying or preventing a third party from acquiring control over or merging with us.

The provisions of our charter documents might inhibit potential acquisition bids that a stockholder might believe are desirable, and the market price of our common stock could be lower as a result.

Our Board of Directors has the authority to issue up to 5,000,000 shares of preferred stock. Our Board of Directors can fix the price, rights, preferences, privileges and restrictions of the preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock might delay or prevent a change in control transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders might be adversely affected. The issuance of preferred stock might result in the loss of voting control to other stockholders. We have no current plans to issue any shares of preferred stock. Our charter documents also contain other provisions, which might discourage, delay or prevent a merger or acquisition, including:

These provisions could also have the effect of discouraging others from making tender offers for our common stock. As a result, these provisions might prevent the market price of our common stock from increasing substantially in response to actual or rumored takeover attempts. These provisions might also prevent changes in our management.

Item 1B.    Unresolved Staff Comments

None.

Item 2.    Properties

Our executive offices, our principal administration, marketing and sales operations and a portion of our research and development operations are located in a 44,277 square foot facility in Sunnyvale, California, which we purchased in fiscal 2010. In addition, we occupy approximately 25,250 square feet in a facility located in Hsin Chu, Taiwan under a lease expiring in August 2017. This facility supports our manufacturing activities. We believe that both our Sunnyvale and Taiwan facilities are adequate for our needs for the foreseeable future. We also lease space in Georgia and Texas. The aggregate annual gross rent for our leased facilities was approximately $354,000 in fiscal 2015.

Item 3.    Legal Proceedings

In March 2011, Cypress Semiconductor Corporation, a semiconductor manufacturer, filed a lawsuit against us in the United States District Court for the District of Minnesota alleging that our products, including our SigmaDDR and SigmaQuad families of Very Fast SRAMs, infringe five patents held by Cypress.  The complaint sought unspecified damages for past infringement and a permanent injunction against future infringement.

On June 10, 2011, Cypress filed a complaint against us with the United States International Trade Commission (the “ITC”).  The ITC complaint, as subsequently amended, alleged infringement by GSI of three of the five patents involved in the District Court case and one additional patent and also alleged infringement by three of our distributors and 11 of our customers who allegedly incorporate our SRAMs in their products.  The ITC complaint sought a limited exclusion order excluding the allegedly infringing SRAMs, and products containing them, from entry into the United States and permanent orders directing GSI and the other respondents to cease and desist from selling or distributing such products in the United States.  On July 21, 2011, the ITC formally instituted an investigation in response to Cypress’s complaint.  On June 7, 2013, the ITC announced that the full Commission had affirmed the determination of Chief Administrative Law Judge Charles E. Bullock that GSI’s SRAM devices, and products containing them, do not infringe the Cypress patents and that Cypress had failed to establish the existence of a domestic industry that practices the patents.  Moreover, the Commission reversed a portion of Judge Bullock’s determination with respect to the validity of the patents, finding the asserted claims of one of the patents to have been anticipated by prior art and, therefore, invalid.  The Commission ordered the investigation terminated, and Cypress did not appeal the ruling.

The Minnesota District Court case had been stayed pending the conclusion of the ITC proceeding.  Following the termination of the ITC proceeding, the stay was lifted.  On May 1, 2013, Cypress filed an additional lawsuit in the United States District Court for the Northern District of California alleging infringement by our products of five additional Cypress patents.  Like the Minnesota case, the complaint in the California lawsuit sought unspecified damages for past infringement and a permanent injunction against future infringement.  We filed answers in both cases denying liability and asserting affirmative defenses.  On August 7, 2013, the parties stipulated that the claims in the Minnesota case with respect to three of the asserted patents would be dismissed without prejudice and that the claims with respect to the remaining two patents would be transferred to the Northern District of California and consolidated with the pending California case.  On August 20, 2013, the Court in the California case ordered the cases consolidated.

On July 22, 2011, we filed a complaint against Cypress in the United States District Court for the Northern District of California.  Our complaint alleged that Cypress had conducted an unlawful combination and conspiracy to monopolize the market for certain high-performance SRAM devices, known as fast synchronous Quad Data Rate

---

 

(or QDR) SRAMs and Double Data Rate (or DDR) SRAMs.  The complaint alleged that the anti-competitive, collusive and conspiratorial conduct of Cypress and certain co-conspirators violated Section 1 of the Sherman Act and also constituted unlawful restraint of trade and unfair competition under applicable provisions of California law.  The complaint sought treble damages, in an amount to be determined at trial, a preliminary and permanent injunction prohibiting the continuation of the unfair and illegal business practices and recovery of GSI’s attorneys’ fees and costs.

On May 6, 2015, the Company and Cypress entered into a settlement agreement to resolve the patent infringement and antitrust litigation.  Under the settlement agreement: 

 

The parties agreed that the settlement agreement was entered into to resolve disputed claims, and that each party denies any liability to the other party.

Item 5.    Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information

Our common stock has traded on the Nasdaq Global Market under the symbol "GSIT" since our initial public offering on March 29, 2007. The following table sets forth, for the periods indicated, the high and low sales prices for our common stock on such market.

 

 

 

 

Holders of Common Stock

On May 29, 2015, the closing price of our common stock on the Nasdaq Global Market was $5.08, and there were 36 holders of record of our common stock. Because many of such shares are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of beneficial holders of our common stock represented by these record holders.

Dividend Policy

We have never declared or paid cash dividends on our common stock. The payment of dividends in the future will be at the discretion of our Board of Directors. However, we currently intend to retain future earnings to finance the growth and development of our business, and we do not anticipate declaring or paying any cash dividends in the foreseeable future.

Securities Authorized for Issuance under Equity Compensation Plans

Please see Part III, Item 12 of this report for information regarding securities authorized for issuance under our equity compensation plans. Such information is incorporated by reference from our definitive proxy statement for our 2015 annual meeting of stockholders.

Issuer Purchases of Equity Securities

Our Board of Directors has authorized us to repurchase, at management’s discretion, shares of our common stock.  On August 20, 2013, the Board increased the dollar value of shares that may be repurchased by $10 million. Under the repurchase program, we may repurchase shares from time to time on the open market or in private transactions. The specific timing and amount of the repurchases will be dependent on market conditions, securities law limitations and other factors. The repurchase program may be suspended or terminated at any time without prior notice.  Below is summary of the repurchases of our common stock made during the quarter ended March 31, 2015, all of which were made under our repurchase program.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations

        The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ substantially from those anticipated in these forward-looking statements as a result of many factors, including those set forth under "Risk Factors" and elsewhere in this report. The following discussion should be read together with our consolidated financial statements and the related notes included elsewhere in this report.

Overview

We are a fabless semiconductor company that designs, develops and markets static random access memories, or SRAMs, that operate at speeds of less than 10 nanoseconds, which we refer to as Very Fast SRAMs, and low

latency dynamic random access memories, or LLDRAMs, primarily for the networking and telecommunications markets. We are subject to the highly cyclical nature of the semiconductor industry, which has experienced significant fluctuations, often in connection with fluctuations in demand for the products in which semiconductor devices are used. Our revenues have been substantially impacted by significant fluctuations in sales to Cisco Systems, historically our largest customer, and more recently to Alcatel-Lucent. We expect that future direct and indirect sales to these two customers will continue to fluctuate significantly on a quarterly basis. The worldwide financial crisis and the resulting economic impact on the end markets we serve have adversely impacted our financial results since the second half of fiscal 2009, and we expect that the unsettled global economic environment will continue to affect our operating results in future periods. However, with no debt, substantial liquidity and a history of positive cash flows from operations, we believe we are in a better financial position than many other companies of our size.

Revenues.    Our revenues are derived primarily from sales of our Very Fast SRAM products. Sales to networking and telecommunications OEMs accounted for 64% to 79% of our net revenues during our last three fiscal years. We also sell our products to OEMs that manufacture products for defense applications such as radar and guidance systems, for professional audio applications such as sound mixing systems, for test and measurement applications such as high-speed testers, for automotive applications such as smart cruise control and voice recognition systems, and for medical applications such as ultrasound and CAT scan equipment.

As is typical in the semiconductor industry, the selling prices of our products generally decline over the life of the product. Our ability to increase net revenues, therefore, is dependent upon our ability to increase unit sales volumes of existing products and to introduce and sell new products with higher average selling prices in quantities sufficient to compensate for the anticipated declines in selling prices of our more mature products.  Although we expect the average selling prices of individual products to decline over time, we believe that, over the next several quarters, our overall average selling prices will increase due to a continuing shift in product mix to a higher percentage of higher price, higher density products. Our ability to increase unit sales volumes is dependent primarily upon increases in customer demand but, particularly in periods of increasing demand, can also be affected by our ability to increase production through the availability of increased wafer fabrication capacity from TSMC and Powerchip, our wafer suppliers, and our ability to increase the number of good integrated circuit die produced from each wafer through die size reductions and yield enhancement activities.

We may experience fluctuations in quarterly net revenues for a number of reasons. Historically, orders on hand at the beginning of each quarter are insufficient to meet our revenue objectives for that quarter and are generally cancelable up to 30 days prior to scheduled delivery. Accordingly, we depend on obtaining and shipping orders in the same quarter to achieve our revenue objectives. In addition, the timing of product releases, purchase orders and product availability could result in significant product shipments at the end of a quarter. Failure to ship these products by the end of the quarter may adversely affect our operating results. Furthermore, our customers may delay scheduled delivery dates and/or cancel orders within specified timeframes without significant penalty.

We sell our products through our direct sales force, international and domestic sales representatives and distributors. Revenues from product sales, except for sales to distributors, are generally recognized upon shipment, net of sales returns and allowances. Sales to consignment warehouses, who purchase products from us for use by contract manufacturers, are recorded upon delivery to the contract manufacturer. Sales to distributors are recorded as deferred revenues for financial reporting purposes and recognized as revenues when the products are resold by the distributors to the OEM. Sales to distributors are made under agreements allowing for returns or credits under certain circumstances. We therefore defer recognition of revenue on sales to distributors until products are resold by the distributor.

Historically, a small number of OEM customers have accounted for a substantial portion of our net revenues, and we expect that significant customer concentration will continue for the foreseeable future. Many of our OEMs use contract manufacturers to manufacture their equipment. Accordingly, a significant percentage of our net revenues is derived from sales to these contract manufacturers and to consignment warehouses. In addition, a significant portion of our sales are made to foreign and domestic distributors who resell our products to OEMs, as well as their contract manufacturers. Direct sales to contract manufacturers and consignment warehouses accounted for 33.1%, 37.5% and 42.0% of our net revenues for fiscal 2015,  2014 and 2013,  respectively. Sales to foreign and domestic distributors accounted for 58.7%, 50.0% and 47.6% of our net revenues for fiscal 2015,  2014 and 2013, respectively. The following direct customers accounted for 10% or more of our net revenues in one or more of the following periods:

 

Alcatel-Lucent was our largest customer in fiscal 2015 and 2014.  Alcatel-Lucent purchases products directly from us and through contract manufacturers and distributors.  Based on information provided to us by Alcatel-Lucent’s contract manufacturers and our distributors, purchases by Alcatel-Lucent represented approximately 25%, 19% and 12% of our net revenues in fiscal 2015,  2014 and 2013, respectively. Cisco Systems, historically our largest OEM customer, purchases our products primarily through its consignment warehouses and also purchases some products through its contract manufacturers and directly from us. Based on information provided to us by Cisco Systems' consignment warehouses and contract manufacturers, purchases by Cisco Systems represented approximately 13%, 19% and 29% of our net revenues in fiscal 2015,  2014 and 2013, respectively.  Our revenues have been substantially impacted by significant fluctuations in sales to Alcatel-Lucent and Cisco Systems, and we expect that future direct and indirect sales to these two customers will continue to fluctuate substantially on a quarterly basis and that such fluctuations may significantly affect our operating results in future periods.  To our knowledge, none of our other OEM customers accounted for more than 10% of our net revenues in fiscal 2015,  2014 or 2013.

Cost of Revenues.    Our cost of revenues consists primarily of wafer fabrication costs, wafer sort, assembly, test and burn-in expenses, the amortized cost of production mask sets, excess and obsolete inventory write-downs, stock-based compensation and the cost of materials and overhead from operations. All of our wafer manufacturing and assembly operations, and a significant portion of our wafer sort testing operations, are outsourced. Accordingly, most of our cost of revenues consists of payments to TSMC, Powerchip and independent assembly and test houses. Because we do not have long-term, fixed-price supply contracts, our wafer fabrication and other outsourced manufacturing costs are subject to the cyclical fluctuations in demand for semiconductors. Cost of revenues also includes expenses related to supply chain management, quality assurance, and final product testing and documentation control activities conducted at our headquarters in Sunnyvale, California and our branch operations in Taiwan.

---

 

Gross Profit.    Our gross profit margins vary among our products and are generally greater on our higher density products and, within a particular density, greater on our higher speed and industrial temperature products. We expect that our overall gross margins will fluctuate from period to period as a result of shifts in product mix, changes in average selling prices and our ability to control our cost of revenues, including costs associated with outsourced wafer fabrication and product assembly and testing.

Research and Development Expenses.    Research and development expenses consist primarily of salaries and related expenses for design engineers and other technical personnel, the cost of developing prototypes, stock-based compensation and fees paid to consultants. We charge all research and development expenses to operations as incurred. We charge mask costs used in production to costs of revenues over a 12-month period. However, we charge costs related to pre-production mask sets, which are not used in production, to research and development expenses at the time they are incurred. These charges often arise as we transition to new process technologies and, accordingly, can cause research and development expenses to fluctuate on a quarterly basis. We believe that continued investment in research and development is critical to our long-term success, and we expect to continue to devote significant resources to product development activities. Accordingly, we expect that our research and development expenses will increase in future periods, although such expenses as a percentage of net revenues may fluctuate.

Selling, General and Administrative Expenses.     Selling, general and administrative expenses consist primarily of commissions paid to independent sales representatives, salaries, stock-based compensation and related expenses for personnel engaged in sales, marketing, administrative, finance and human resources activities, professional fees, costs associated with the promotion of our products and other corporate expenses. We expect that our sales and marketing expenses will increase in absolute dollars in future periods if we are able to grow and expand our sales force but that, to the extent our revenues increase in future periods, these expenses will generally decline as a percentage of net revenues. We also expect that, in support of any future growth that we are able to achieve, general and administrative expenses will generally increase in absolute dollars.  General and administrative expenses increased significantly beginning in fiscal 2012 as a result of substantial legal expenses, principally related to our patent infringement and antitrust litigation with Cypress Semiconductor Corporation.  These expenses varied significantly from quarter to quarter thereafter, depending on the relative level of activity in the Cypress litigation.  They were substantially reduced during the six months ended September 30, 2012 while the issuance of the initial determination in the ITC proceeding was pending. They increased again in the following quarters as the parties filed and responded to petitions for review of the initial determination, activities related to the antitrust litigation with Cypress entered the discovery phase, activity resumed in the federal court patent litigation that had been stayed pending the conclusion of the ITC proceeding, and we began to incur expenses in unrelated commercial and trade secret litigation in which we are the plaintiff.  In May 2015, we entered into a settlement agreement to resolve our protracted litigation with Cypress. See “Part I.  Item 3. Legal Proceedings.”  Although we will cease to incur legal expenses related to our litigation with Cypress after the quarter ending June 30, 2015, we expect that legal expenses associated with the unrelated pending litigation will be substantial over the next several quarters as activity in that case ramps up in anticipation of trial currently scheduled for October 2015.

Results of Operations

The following table sets forth statement of operations data as a percentage of net revenues for the periods indicated:

 

Fiscal Year Ended March 31, 2015 Compared to Fiscal Year Ended March 31, 2014

Net Revenues.    Net revenues decreased by 8.7% from $58.6 million in fiscal 2014 to $53.5 million in fiscal 2015. The reduction reflected the continuing weakness in the global networking and telecommunications markets and, in particular, continued weakness in Asia.  Direct and indirect sales to Alcatel-Lucent, currently our largest customer, increased by $2.0 million from $11.2 million in fiscal 2014 to $13.2 million fiscal 2015. However, direct and indirect sales to Cisco Systems, historically our largest customer, decreased by $3.9 million from $11.0 million in fiscal 2014 to $7.1 million in fiscal 2015 due to softness in the market for its switches and routers that incorporate our products. We believe that our net revenues in each of these periods were also negatively impacted by uncertainty regarding the outcome of our patent litigation with Cypress Semiconductor.  We believe that the Commission’s favorable determination in the ITC proceeding in June 2013 reduced this market uncertainty, although some design-in losses that we suffered during the pendency of the ITC proceeding will continue to adversely affect our revenues throughout the life of the related products.  Shipments of our SigmaQuad product line accounted for 41.6% of total shipments in fiscal 2015 compared to 42.2% of total shipments in fiscal 2014.

Cost of Revenues.    Cost of revenues decreased by 12.6% from $32.5 million in fiscal 2014 to $28.4 million in fiscal 2015. This decrease was primarily due to the corresponding decrease in net revenues, favorable product mix and reductions in variable manufacturing costs in fiscal 2015,  in addition to a decrease of $1.0 million in non-cash write-downs of excess or obsolete inventory compared to fiscal 2014. A write-down of $985,000 was taken in the three months ended December 31, 2013 to reflect the fact that management’s prior expectations of increasing demand for our products, following the favorable ITC ruling in June  2013 and the exit of a competitor from the SRAM market in the December 2012 quarter, did not materialize.  Cost of revenues included stock-based compensation expense of $401,000 and $386,000, respectively, in fiscal 2015 and fiscal 2014.  

Gross Profit.    Gross profit decreased by 3.8% from $26.1 million in fiscal 2014 to $25.1 million in fiscal 2015.  However, gross margin increased from 44.6% in fiscal 2014 to 47.0% in fiscal 2015.  The decrease in gross profit was related to the corresponding decrease in net revenues, while the improvement in gross margin was due to

---

 

favorable changes in the mix of products and customers and the reduction in the non-cash write-down of excess or obsolete inventory.

Research and Development Expenses.    Research and development expenses decreased 9.1% from $13.1 million in fiscal 2014 to $11.9 million in fiscal 2015.  This decrease was primarily due to decreases of $1.5 million in expenses related to pre-production mask sets, a $177,000 decrease in depreciation expense and lesser decreases in repairs and maintenance expense and patent-related expenses, partially offset by an increase of $567,000 in payroll-related expenses. Research and development expenses included stock-based compensation expense of $941,000 and $970,000, respectively, in fiscal 2015 and fiscal 2014.

Selling, General and Administrative Expenses.    Selling, general and administrative expenses increased 2.3% from  $18.8 million in fiscal 2014 to $19.2 million in fiscal 2015. This increase was primarily related to increases of $346,000 in payroll-related expenses and $308,000 in non-legal professional fees and lesser increases in travel related expenses and legal fees related to the patent infringement and antitrust litigation involving Cypress Semiconductor Corporation and other pending litigation, partially offset by decreases in stock-based compensation expense and independent sales representative commissions.  Selling, general and administrative expenses included stock-based compensation expense of $735,000 and $872,000, respectively, in fiscal 2015 and fiscal 2014.  

Interest and Other Income (Expense), Net.  Interest and other income (expense), net increased 14.8% from $338,000 in fiscal 2014 to $388,000 in fiscal 2015.  Interest income decreased by $63,000 due to lower interest rates received on reduced balances of cash and short-term and long-term investments.  These decreases were more than offset by a foreign currency exchange gain of $64,000 in fiscal 2015 compared to a foreign currency exchange loss of $49,000 in fiscal 2014.  The exchange gain or loss in each period was related to our Taiwan branch operations.

Provision for Income Taxes.    The provision for income taxes of $713,000 in fiscal 2014 compared to a benefit of $675,000 in fiscal 2015. Because we recorded a cumulative three-year loss on a U.S. tax basis for the year ended March 31, 2015, we recorded a tax provision reflecting a full valuation allowance of our $6.0 million in deferred tax assets in fiscal 2015.

Net Income (Loss).    Net loss decreased from $6.2 million in fiscal 2014 to $5.0 million in fiscal 2015. This decrease was primarily due to the changes in net revenues, gross profit and operating expenses discussed above.

Fiscal Year Ended March 31, 2014 Compared to Fiscal Year Ended March 31, 2013

Net Revenues.    Net revenues decreased by 11.3% from $66.0 million in fiscal 2013 to $58.6 million in fiscal 2014. The reduction reflected the continued slowness in the global networking and telecommunications markets and in particular, continued weak sales in Asia. Direct and indirect sales to Cisco Systems, historically our largest customer, decreased by $8.3 million from $19.3 million in fiscal 2013 to $11.0 million in fiscal 2014 due to softness in the market for its switches and routers that incorporate our products.    Direct and indirect sales to Alcatel-Lucent increased by $3.1 million from $8.1 million in fiscal 2013 to $11.2 million fiscal 2014.  We believe that our net revenues in each of these periods were also negatively impacted by uncertainty regarding the outcome of our pending patent litigation with Cypress Semiconductor.  Shipments of our SigmaQuad product line accounted for 42.2% of total shipments in fiscal 2014 compared to 36.1% of total shipments in fiscal 2013.

Cost of Revenues.    Cost of revenues decreased by 13.2% from $37.4 million in fiscal 2013 to $32.5 million in fiscal 2014. This decrease was primarily due to the corresponding decrease in net revenues, favorable product mix and reductions in variable manufacturing costs in fiscal 2014, offset by an increase of $1.3 million in non-cash write-downs of excess or obsolete inventory in fiscal 2014. The increased write-downs were taken to reflect the fact that management’s prior expectations of increasing demand for our products, following the favorable ITC ruling in June 2013 and the exit of a competitor from the SRAM market in the December 2012 quarter, did not materialize.

---

 

Cost of revenues included stock-based compensation expense of $386,000 and $338,000, respectively, in fiscal 2014 and fiscal 2013.  

Gross Profit.    Gross profit decreased by 8.7% from $28.6 million in fiscal 2013 to $26.1 million in fiscal 2014.  Gross margin increased from 43.3% in fiscal 2013 to 44.6% in fiscal 2014.  The decrease in gross profit was primarily related to the decrease in net revenues.    The change in gross margin was primarily related to changes in the mix of products and customers, the reduction in variable manufacturing expenses and the write-down of excess inventory discussed above.

Research and Development Expenses.    Research and development expenses increased 14.3% from $11.5 million in fiscal 2013 to $13.1 million in fiscal 2014.  This increase was primarily due to an increase of $1.5 million in expenses related to pre-production mask sets and an increase of $338,000 in payroll related expenses, partially offset by decreases in stock-based compensation expense and facilities related expenses.  Research and development expenses included stock-based compensation expense of $970,000 and $1,140,000, respectively, in fiscal 2014 and fiscal 2013.

Selling, General and Administrative Expenses.    Selling, general and administrative expenses increased 37.4% from  $13.7 million in fiscal 2013 to $18.8 million in fiscal 2014. This increase was primarily related to an increase of $5.6 million in legal fees related to the pending patent infringement and antitrust litigation involving Cypress Semiconductor Corporation and other pending litigation, partially offset by decreases in independent sales representative commissions, non-legal professional fees and stock-based compensation expense.  Selling, general and administrative expenses included stock-based compensation expense of $872,000 and $800,000, respectively, in fiscal 2014 and fiscal 2013.  

Interest and Other Income (Expense), Net.  Interest and other income (expense), net decreased 27.2% from $464,000 in fiscal 2013 to $338,000 in fiscal 2014.  Interest income decreased by $68,000 due to lower interest rates received on our cash and short-term and long-term investments.  In addition, we recorded a foreign currency exchange loss of $49,000 in fiscal 2014 compared to a foreign currency exchange gain of $9,000 in fiscal 2013.  The exchange gain or loss in each period was related to our Taiwan branch operations.

Provision for Income Taxes.    The provision for income taxes increased from $38,000 in fiscal 2013 to $713,000 in fiscal 2014.  Because we recorded a cumulative three-year loss on a U.S. tax basis for the period ended March 31, 2014, we recorded a tax provision reflecting a full valuation allowance of our $3.7 million in deferred tax assets.

Net Income (Loss).    Net income decreased from $3.8 million in fiscal 2013 to a net loss of $6.2 million in fiscal 2014. This decrease was primarily due to the decreased net revenues, changes in operating expenses and our income tax provision discussed above.

Liquidity and Capital Resources

As of March 31, 2015, our principal sources of liquidity were cash, cash equivalents and short-term investments of $59.0 million compared to $80.9 million as of March 31, 2014.

Net cash provided by operating activities was $1.1 million for fiscal 2015 compared to $8.4 million for fiscal 2014 and $14.7 million for fiscal 2013. The primary sources of cash in fiscal 2015 were a decrease in prepaid expenses and other assets of $2.9 million, non-cash stock-based compensation expense of $2.1 million,  depreciation and amortization expense of $1.6 million and a provision for excess and obsolete inventory of $1.1 million. The primary uses of cash in fiscal 2015 were a net loss of $5.0 million, a decrease of $1.9 million in accounts payable and an increase of $1.3 million in inventories.    The primary sources of cash in fiscal 2014 were a reduction in

---

 

inventory of $3.5 million, adjustments for non-cash stock-based compensation expense of $2.2 million, a provision for excess and obsolete inventory of $2.1 million and depreciation expense of $2.0 million, partially offset by a net loss of $6.2 million and a decrease in accrued expenses and other liabilities.  We allowed inventory levels to decrease in response to the slowdown in our business during fiscal 2013 and fiscal 2014. The primary sources of cash in fiscal 2013 were net income of $3.8 million, a reduction in inventory of $2.1 million and a reduction in prepaid expenses of $2.5 million, offset by a decrease in accounts payable of $1.6 million.    The decrease in accounts payable in fiscal 2013 was primarily due to decreased legal expenses related to the pending patent infringement and antitrust litigation involving Cypress Semiconductor Corporation compared to fiscal 2012. 

Net cash provided by investing activities was $23.2 million in fiscal 2015 compared to net cash used by investing activities of $8.2 million in fiscal 2014 and $2.5 million in fiscal 2013.  Investment activities in fiscal 2015 consisted primarily of the sale and maturity of corporate notes and certificates of deposits of $39.7 million, partially offset by the purchase of investments of $16.0 million.  Investment activities in fiscal 2014 consisted primarily of the purchase of agency bonds, state and municipal obligations, corporate notes and certificates of deposit of $35.9 million, substantially offset by proceeds from the sales and maturities of investments of $28.4 million. Investment activities in fiscal 2013 consisted primarily of the purchase of state and municipal obligations, corporate notes and certificates of deposit of $35.6 million, substantially offset by sales and maturities of investments of $33.4 million.    

   Cash used in financing activities in fiscal 2015,  fiscal 2014 and in fiscal 2013 included the repurchase of our common stock for a total purchase price of $30.0 million, $2.9 million and $3.6 million, respectively. We repurchased 4,661,775 shares of our common stock at an average price of $6.33 per share in fiscal 2015.  Cash provided by financing activities in fiscal 2015, fiscal 2014 and fiscal 2013 primarily consisted of the net proceeds from the sale of common stock pursuant to our employee stock plans.

At March 31, 2015, we had total minimum lease obligations of approximately $619,000 from April 1, 2015 through August 31, 2017, under non-cancelable operating leases.

We believe that our existing balances of cash, cash equivalents and short-term investments, and cash flow expected to be generated from our future operations, will be sufficient to meet our cash needs for working capital and capital expenditures for at least the next 12 months, although we could be required, or could elect, to seek additional funding prior to that time. Our future capital requirements will depend on many factors, including the rate of revenue growth that we experience, the extent to which we utilize subcontractors, the levels of inventory and accounts receivable that we maintain, the timing and extent of spending to support our product development efforts and the expansion of our sales and marketing efforts. Additional capital may also be required for the consummation of any acquisition of businesses, products or technologies that we may undertake. We cannot assure you that additional equity or debt financing, if required, will be available on terms that are acceptable or at all.

Contractual Obligations

The following table describes our contractual obligations as of March 31, 2015:

 

 

---

 

As of March 31, 2015, the current portion of our unrecognized tax benefits was $0, and the long-term portion was $780,000. We do not expect to make federal income tax payments in the next twelve months, and we are not able to make a reasonably reliable estimate of the timing of such payments due to uncertainties in the timing of tax credit outcomes.

Critical Accounting Policies and Estimates

The preparation of our consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States ("GAAP") requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are inherent in the preparation of the consolidated financial statements and include estimates affecting revenue recognition, obsolete and excess inventory, the valuation allowance on deferred tax assets, the valuation of equity instruments and stock-based compensation. We believe that we consistently apply these judgments and estimates and that our financial statements and accompanying notes fairly represent our financial results for all periods presented. However, any errors in these judgments and estimates may have a material impact on our balance sheet and statement of operations. Critical accounting estimates, as defined by the Securities and Exchange Commission, are those that are most important to the portrayal of our financial condition and results of operations and require our most difficult and subjective judgments and estimates of matters that are inherently uncertain. Our critical accounting estimates include those regarding revenue recognition, the valuation of inventories, taxes and stock-based compensation.

Revenue Recognition.    We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability of the resulting receivable is reasonably assured. Under these criteria, revenue from the sale of our products is generally recognized upon shipment according to our shipping terms, net of accruals for estimated sales returns and allowances based on historical experience. Sales to distributors are made under agreements allowing for returns or credits. We defer recognition of revenue on sales to distributors until products are resold by the distributor to the end-user. Distributors have stock rotation, price protection and ship from stock pricing adjustment rights, and we therefore defer recognition of revenue on sales to distributors until products are resold by the distributor. In light of uncertainties related to the stock rotation rights and possible changes to sales prices resulting from price protection and price adjustment rights granted, we are unable to reasonably estimate possible changes and the resulting sales price to the distributor is not fixed or determinable until the final sale to the end user. Sales to consignment warehouses, who purchase products from us for use by contract manufacturers, are recorded upon delivery to the contract manufacturers.

The timing of recognizing revenues on product sales to distributors is dependent on receiving pertinent and accurate data from our distributors in a timely fashion. Distributors provide us monthly data regarding the product, price, quantity, and end customer for their shipments as well as the quantities of our products they have in stock at month end. In determining the appropriate amount of revenue to recognize, we use this data in reconciling differences between our estimate of their inventory levels and their reported inventories and shipment activities. If distributors incorrectly report their inventories or shipment activities, it could lead to inaccurate reporting of our revenues and income.

Valuation of Inventories.    Inventories are stated at the lower of cost or market value, cost being determined on a weighted average basis. Our inventory write-down allowance is established when conditions indicate that the selling price of our products could be less than cost due to physical deterioration, obsolescence, changes in price levels, or other causes. We consider the need to establish the allowance for excess inventory generally based on inventory levels in excess of 12 months of forecasted demand for each specific product. Inventory consists of finished goods at our premises or consignment warehouses, work in progress at our premises or our contract

---

 

manufacturers and finished goods at distributors and takes into account any uncancellable purchase commitments. Historically, it has been difficult to forecast customer demand especially at the part-number level. Many of the orders we receive from our customers and distributors request delivery of product on relatively short notice and with lead times less than our manufacturing cycle time. In order to provide competitive delivery times to our customers, we build and stock a certain amount of inventory in anticipation of customer demand that may not materialize. Moreover, as is common in the semiconductor industry, we may allow customers to cancel orders with minimal advance notice. Thus, even product built to satisfy specific customer orders may not ultimately be required to fulfill customer demand. Nevertheless, at any point in time, some portion of our inventory is subject to the risk of being materially in excess of our projected demand. Additionally, our average selling prices could decline due to market or other conditions, which creates a risk that costs of manufacturing our inventory may not be recovered. These factors contribute to the risk that we may be required to record additional inventory write-downs in the future, which could be material. In addition, if actual market conditions are more favorable than expected, inventory previously written down may be sold to customers resulting in lower cost of sales and higher income from operations than expected in that period.

Taxes.    We account for income taxes under the liability method, whereby deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. We make certain estimates and judgments in the calculation of tax liabilities and the determination of deferred tax assets, which arise from temporary differences between tax and financial statement recognition methods. We record a valuation allowance to reduce our deferred tax assets to the amount that management estimates is more likely than not to be realized. As of March 31, 2015,  our net deferred tax assets of $6.0 million are subject to a full valuation allowance. If, in the future we determine that we are likely to realize all or part of our net deferred tax assets, an adjustment to deferred tax assets would be added to earnings in the period such determination is made.

In addition, the calculation of tax liabilities involves inherent uncertainty in the application of complex tax laws. We record tax reserves for additional taxes that we estimate we may be required to pay as a result of future potential examinations by federal and state taxing authorities. If the payment ultimately proves to be unnecessary, the reversal of these tax reserves would result in tax benefits being recognized in the period we determine such reserves are no longer necessary. If an ultimate tax assessment exceeds our estimate of tax liabilities, an additional charge to provision for income taxes will result.

Authoritative guidance prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return (including a decision whether to file or not to file a return in a particular jurisdiction). Under this guidance, the financial statements will reflect expected future tax consequences of such positions presuming the taxing authorities' full knowledge of the position and all relevant facts, but without considering time values.

Stock-Based Compensation.    Under authoritative guidance, stock-based compensation expense recognized in the statement of operations is based on options ultimately expected to vest, reduced by the amount of estimated forfeitures. We chose the straight-line method of allocating compensation cost over the requisite service period of the related award in accordance with the authoritative guidance. We calculated the expected term based on the historical average period of time that options were outstanding as adjusted for expected changes in future exercise patterns, which, for options granted in fiscal 2015,  2014 and 2013, resulted in an expected term of approximately five years. We used historical volatility to estimate expected volatility in fiscal 2015, 2014 and 2013. The risk-free interest rate is based on the U.S. Treasury yields in effect at the time of grant for periods corresponding to the expected life of the options. The dividend yield is 0%, based on the fact that we have never paid dividends and have no present intention to pay dividends. Determining some of these assumptions requires significant judgment and

---

 

changes to these assumptions could result in a significant change to the calculation of stock-based compensation in future periods.

Cash flows, if any, resulting from the tax benefits from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) are classified as financing cash flows.

As stock-based compensation expense recognized in the Consolidated Statement of Operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. We estimate forfeitures at the time of grant and revise the original estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

We have no stock-based compensation arrangements with non-employees except for stock options granted to our non-employee directors.

Off-Balance Sheet Arrangements

At March 31, 2015, we did not have any off-balance sheet arrangements or relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Accordingly, we are not exposed to the type of financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

Recent Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance related to our responsibility to evaluate whether there is substantial doubt about our ability to continue ongoing business operations and to provide relevant footnote disclosures. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." The new accounting standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The accounting standard is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016. Early adoption is not permitted. ASU No. 2014-09 provides for one of two methods of transition: retrospective application to each prior period presented; or recognition of the cumulative effect of retrospective application of the new standard in the period of initial application.  On April 1, 2015, the FASB proposed a one year deferral of the effective date to December 15, 2017, with early application permitted, but not before the original effective date of December 15, 2016. We are currently evaluating the impact of this accounting standard on our consolidated financial statements.

In July 2013, the FASB issued an Accounting Standards Update (“ASU”) on Income Taxes, to improve the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This guidance is expected to reduce diversity in practice and is expected to better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. Implementation of this guidance in the year ended March 31, 2015 did not have a material impact our financial position or results of operations.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Exchange Risk.    Our revenues and expenses, except those expenses related to our operations in Taiwan, including subcontractor manufacturing expenses, are denominated in U.S. dollars. As a result, we have relatively little exposure for currency exchange risks, and foreign exchange losses have been minimal to date. We do not currently enter into forward exchange contracts to hedge exposure denominated in foreign currencies or any other derivative financial instruments for trading or speculative purposes. In the future, if we feel our foreign currency exposure has increased, we may consider entering into hedging transactions to help mitigate that risk.

Interest Rate Sensitivity.    We had cash, cash equivalents, short term investments and long-term investments totaling $80.7 million at March 31, 2015. These amounts were invested primarily in money market funds, state and municipal obligations, corporate notes,  certificates of deposit and agency bonds. The cash, cash equivalents and short-term marketable securities are held for working capital purposes. We do not enter into investments for trading or speculative purposes. Due to the short-term nature of these investments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. We believe a hypothetical 100 basis point increase in interest rates would not materially affect the fair value of our interest-sensitive financial instruments. Declines in interest rates, however, will reduce future investment income.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of GSI Technology, Inc.:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows present fairly, in all material respects, the financial position of GSI Technology, Inc. and its subsidiaries at March 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended March 31, 2015 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting under item 9A. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits.  We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects.  Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.  Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.  A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company

GSI Technology, Inc. (the "Company") was incorporated in California in March 1995 and reincorporated in Delaware on June 9, 2004. The Company is a provider of "Very Fast" SRAM products and LLDRAM products that are incorporated primarily in high-performance networking and telecommunications equipment, such as routers, switches, wide area network infrastructure equipment, wireless base stations and network access equipment. In addition, the Company serves the ongoing needs of the military, industrial, test equipment and medical markets for high-performance SRAMs.

Accounting principles

The consolidated financial statements and accompanying notes were prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

Basis of consolidation

The consolidated financial statements include the accounts of the Company's three wholly-owned subsidiaries, GSI Technology Holdings, Inc., GSI Technology (BVI), Inc. and GSI Technology Taiwan, Inc.  All significant inter-company transactions and balances have been eliminated in consolidation.

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are inherent in the preparation of the consolidated financial statements and include revenue recognition, obsolete and excess inventory, the valuation allowance on deferred tax assets, the valuation of equity instruments and stock-based compensation. Actual results could differ from those estimates.

Risk and uncertainties

The Company buys all of its SRAM and LLDRAM wafers, integral components of its products, from single suppliers and is also dependent on independent suppliers to assemble and test its products. During the years ended March 31, 2015,  2014 and 2013, all of the wafers used in the Company's SRAM and LLDRAM products were supplied by Taiwan Semiconductor Manufacturing Company Limited, or TSMC, and Powerchip Technology Corporation, or Powerchip, respectively. If these suppliers fail to satisfy the Company's requirements on a timely basis at competitive prices, the Company could suffer manufacturing delays, a possible loss of revenues, or higher cost of revenues, any of which could adversely affect operating results.

A majority of the Company's net revenues come from sales to customers in the networking and telecommunications equipment industry. A decline in demand in this industry could have a material adverse affect on the Company's operating results and financial condition.

Because much of the manufacturing and testing of the Company's products is conducted in Taiwan, its business performance may be affected by changes in Taiwan's political, social and economic environment. For example, any political instability resulting from the relationship among the United States, Taiwan and the People's Republic of China could damage the Company's business. Moreover, the role of the Taiwanese government in the Taiwanese economy is significant. Taiwanese policies toward economic liberalization, and laws and policies

---

 

affecting technology companies, foreign investment, currency exchange rates, taxes and other matters could change, resulting in greater restrictions on the Company's and its suppliers' ability to do business and operate facilities in Taiwan. If any of these risks were to occur, the Company's business could be harmed.

Some of the Company's suppliers and the Company's two principal operations are located near fault lines. In the event of a major earthquake or other natural disaster near the facilities of any of these suppliers or the Company, the Company's business could be harmed.

From time to time, the Company is involved in legal actions.  See Note 6 for information regarding litigation that was pending at March 31, 2015 and Note 12 regarding its subsequent resolution.  There are many uncertainties associated with any litigation, and the Company may not prevail.  If information becomes available that causes us to determine that a loss in any of our pending litigation, or the settlement of such litigation, is probable, and we can reasonably estimate the loss associated with such events, we will record the loss in accordance with GAAP. However, the actual liability in any such litigation may be materially different from our estimates, which could require us to record additional costs.

Revenue recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability of the resulting receivable is reasonably assured. Under these criteria, revenue from the sale of products is generally recognized upon shipment according to the Company's shipping terms, net of accruals for estimated sales returns and allowances based on historical experience. Sales to distributors are made under agreements allowing for returns or credits. Distributors have stock rotation, price protection and ship from stock pricing adjustment rights and the Company therefore defers recognition of revenue on sales to distributors until products are resold by the distributor. In light of possible changes to sales prices resulting from price protection and price adjustment rights granted, sales prices to the distributor are not fixed or determinable until the final sale to the end user. For sales to consignment warehouses, who purchase products from the Company for use by contract manufacturers, revenues are recognized upon delivery to the contract manufacturer.

Cash and cash equivalents

Cash and cash equivalents include cash in demand accounts and highly liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase, stated at cost, which approximates their fair market value.

Short-term and long-term investments

All of the Company's short-term and long-term investments are classified as available-for-sale. Available-for-sale debt securities with maturities greater than twelve months are classified as long-term investments when they are not intended for use in current operations. Investments in available-for-sale securities are reported at fair value with unrecognized gains (losses), net of tax, as a component of "Accumulated other comprehensive income" on the Consolidated Balance Sheets. The Company monitors its investments for impairment periodically and records appropriate reductions in carrying values when the declines in fair value are determined to be other-than-temporary.

Concentration of credit risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash, cash equivalents, short-term and long-term investments and accounts receivable. The Company places its cash primarily in checking, certificate of deposit, and money market accounts with reputable financial institutions. The Company's accounts receivable are derived primarily from revenue earned from customers located in the U.S.

---

 

and Asia. The Company performs ongoing credit evaluations of its customers' financial condition and, generally, requires no collateral from its customers. The Company maintains an allowance for doubtful accounts receivable based upon the expected collectability of accounts receivable. There were no write offs of accounts receivable in the years ended March 31, 2015, 2014 or 2013.

At March 31, 2015, four customers accounted for 25%,  20%,  16%, and 13% of accounts receivable, and for the year then ended, three customers accounted for 35%,  13%, and 12% of net revenues.  At March 31, 2014, four customers accounted for 20%,  16%,  14%, and 12% of accounts receivable, and for the year then ended, four customers accounted for 30%,  14%,  12% and 10% of net revenues.  At March 31, 2013, six customers accounted for 20%,  16%,  15%,  10%,  10% and 10% of accounts receivable, and for the year then ended, four customers accounted for 27%,  14%,  11% and 10% of net revenues.

Inventories

Inventories are stated at the lower of cost or market value, cost being determined on a weighted average basis. Inventory write-down allowances are established when conditions indicate that the selling price could be less than cost due to physical deterioration, obsolescence, changes in price levels, or other causes. These allowances, once recorded, result in a new cost basis for the related inventory. These allowances are also considered for excess inventory generally based on inventory levels in excess of 12 months of forecasted demand, as estimated by management, for each specific product. The allowance is not reversed until the inventory is sold or disposed of.

The Company recorded write-downs of excess and obsolete inventories of $1.1 million, $2.1 million and $777,000, respectively, in fiscal 2015,  2014 and 2013.  

Property and equipment, net

Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as presented below:

 

Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful lives of the assets or the remaining lease term of the respective assets. Gains or losses on disposals of property and equipment are recorded within income from operations. Costs of repairs and maintenance are typically included as part of operating expenses unless they are incurred in relation to major improvements to existing property and equipment, at which time they are capitalized.

Impairment of long-lived assets

Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that their net book value may not be recoverable. If the sum of the expected future cash flows (undiscounted and before interest) from the use of the assets is less than the net book value of the asset an impairment exists and the amount of the impairment loss, if any, will generally be measured as the difference

---

 

between net book value of the assets and their estimated fair values. There were no impairment losses recognized during the years ended March 31, 2015,  2014 or 2013.

Intangible assets

Intangible assets are amortized over their estimated useful lives, generally on a straight-line basis over five to nine years. The Company reviews identifiable amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset over its fair value.

Research and development

Research and development expenses are related to new product designs, including, salaries, stock-based compensation, contractor fees, and allocation of corporate costs and are charged to the statement of operations as incurred.

Income taxes

The Company accounts for income taxes under the liability method, whereby deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when it is more likely than not that the deferred tax asset will not be realized. Because the Company recorded a cumulative three-year loss on a U.S. tax basis for the year ended March 31, 2015, the Company recorded a tax provision reflecting a full valuation allowance of our $6.0 million in deferred tax assets.

Authoritative guidance prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return (including a decision whether to file or not to file a return in a particular jurisdiction). Under the guidance, the financial statements will reflect expected future tax consequences of such positions presuming the taxing authorities' full knowledge of the position and all relevant facts, but without considering time values. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation process, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement.

Shipping and handling costs

The Company records costs related to shipping and handling in cost of revenues.

Advertising expense

Advertising costs are charged to expense in the period incurred. Advertising expense was $5,000,  $7,000 and $10,000 for the years ended March 31, 2015,  2014, and 2013, respectively.

Foreign currency transactions

The U.S. dollar is the functional currency for all of the Company's foreign operations. Foreign currency transaction gains and losses, resulting from transactions denominated in currencies other than U.S. dollars are

---

 

included in the Consolidated Statements of Operations. These gains and losses were not material for the years ended March 31, 2015,  2014 or 2013.

Segments

The Company operates as one segment for the design, development and sale of integrated circuits.

Accounting for stock-based compensation

Stock-based compensation expense recognized in the Consolidated Statement of Operations is based on options ultimately expected to vest, reduced by the amount of estimated forfeitures. The Company chose the straight-line method of allocating compensation cost over the requisite service period of the related award according to authoritative guidance. The Company calculated the expected term based on the historical average period of time that options were outstanding as adjusted for expected changes in future exercise patterns, which, for options granted in fiscal 2015, 2014 and 2013 resulted in an expected term of approximately five years. The Company used historical volatility to estimate expected volatility in fiscal 2015, 2014 and 2013.  The risk-free interest rate is based on the U.S. Treasury yields in effect at the time of grant for periods corresponding to the expected life of the options. The dividend yield is 0%, based on the fact that the Company has never paid dividends and has no present intention to pay dividends. Changes to these assumptions may have a significant impact on the results of operations.

Authoritative guidance requires cash flows, if any, resulting from the tax benefits from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) to be classified as financing cash flows.

Comprehensive income (loss)

Comprehensive income (loss) is defined to include all changes in stockholders’ equity during a period except those resulting from investments by owners and distributions to owners. For the years ended March 31, 2015,  2014 and 2013, comprehensive income (loss) was $(4,985,000), $(6,201,000) and $3,803,000, respectively.

Recent accounting pronouncements

In August 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance related to the Company’s responsibility to evaluate whether there is substantial doubt about its ability to continue ongoing business operations and to provide relevant footnote disclosures. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." The new accounting standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The accounting standard is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016. Early adoption is not permitted. ASU No. 2014-09 provides for one of two methods of transition: retrospective application to each prior period presented; or, recognition of the cumulative effect of retrospective application of the new standard in the period of initial application.  On April 1, 2015, the FASB proposed a one year deferral of the effective date to December 15, 2017, with early application permitted, but not before the original effective date of December 15, 2016. The Company is currently evaluating the impact of this accounting standard on its consolidated financial statements.

In July 2013, the FASB issued an Accounting Standards Update (“ASU”) on Income Taxes, to improve the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This guidance is expected to reduce diversity in practice and is expected to better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. Implementation of this guidance in the year ended March 31, 2015 did not have a material impact on the Company’s financial position or results of operations.

NOTE 2—NET INCOME (LOSS) PER COMMON SHARE

The Company uses the treasury stock method to calculate the weighted average shares used in computing diluted net income per share. The following table sets forth the computation of basic and diluted net income (loss) per share:

The following shares of common stock underlying outstanding stock options, determined on a weighted average basis, were excluded from the computation of diluted net income (loss) per common share as they had an anti-dilutive effect:

Depreciation and amortization expense was $1,633,000,  $1,981,000 and $2,375,000 for the years ended March 31, 2015,  2014 and 2013, respectively.

 

The following table summarizes the components of intangible assets and related accumulated amortization balances at March 31, 2015 (in thousands):

 

 

Amortization of intangible assets of $171,000 was included in cost of revenues for the year ended March 31, 2015.

As of March 31, 2015, the estimated future amortization expense of intangible assets in the table above is as follows (in thousands):

 

 

 

 

 

 

NOTE 4—INCOME TAXES

Income (loss) before income taxes and income tax expense consists of the following:

 

 

---

 

Income tax expense differs from the amount of income tax determined by applying the applicable U.S. statutory income tax rate to pre-tax income as follows:

 

 

Deferred tax assets and deferred tax liabilities consist of the following:

 

 

U.S. income taxes and withholding taxes have not been provided on a cumulative total of $39.5 million of undistributed earnings for certain non-U.S. subsidiaries. The Company currently intends to indefinitely reinvest these earnings in operations outside the United States.  No provision has been made for taxes that might be payable upon remittance of such earnings, nor is it practicable to determine the amount of such potential liability.

The current portion of the Company's unrecognized tax benefits at March 31, 2015 and 2014  was $0 and $0, respectively. The long-term portion at March 31, 2015 and 2014 was $780,000 and $1,462,000, respectively, of which the timing of the resolution is uncertain. As of March 31, 2015,  $1,277,000 of unrecognized tax benefits had

---

 

been recorded as a reduction to net deferred tax assets. As of March 31, 2015, our net deferred tax assets of $6.0 million are subject to a full valuation allowance. It is possible, however, that some months or years may elapse before an uncertain position for which the Company has established a reserve is resolved. A reconciliation of unrecognized tax benefits is as follows:

 

 

The unrecognized tax benefit balance as of March 31, 2015 of $1,982,000 would affect the Company's effective tax rate if recognized.

Management believes that it is reasonably possible that within the next twelve months the Company could have a reduction in uncertain tax benefits of up to $729,000, including interest and penalties, as a result of the lapse of statute of limitations.

The Company's policy is to include interest and penalties related to unrecognized tax benefits within the provision for income taxes in the Consolidated Statements of Operations.

The Company is subject to taxation in the United States and various state and foreign jurisdictions.  As of March 31, 2015, the Company maintains a full valuation allowance of $6.0 million for deferred tax assets that are not expected to be utilized in future years. Fiscal years 2012 through 2015 remain open to examination by the federal tax authorities and fiscal years 2010 through 2015 remain open to examination by California.

NOTE 5—FINANCIAL INSTRUMENTS

Fair value measurements

Authoritative accounting guidance for fair value measurements provides a framework for measuring fair value and related disclosure.  The guidance applies to all financial assets and financial liabilities that are measured on a recurring basis.  The guidance requires fair value measurement to be classified and disclosed in one of the following three categories:

Level 1: Valuations based on quoted prices in active markets for identical assets and liabilities. The fair value of available-for-sale securities included in the Level 1 category is based on quoted prices that are readily and regularly available in an active market. As of March 31, 2015, the Level 1 category included money market funds of $4.4 million, which were included in cash and cash equivalents on the Consolidated Balance Sheets.

Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly. The fair value of available-for-sale securities included in the Level 2 category is based on the market values obtained from an independent pricing service that were evaluated using pricing models that

---

 

vary by asset class and may incorporate available trade, bid and other market information and price quotes from well established independent pricing vendors and broker-dealers. As of March 31, 2015, the Level 2 category included short-term investments of $22.2 million and long term-investments of $21.7 million, which were primarily comprised of certificates of deposit, corporate debt securities and government and agency securities.

Level 3: Valuations based on inputs that are unobservable and involve management judgment and the reporting entity's own assumptions about market participants and pricing. As of March 31, 2015, the Company had no Level 3 financial assets measured at fair value on the Consolidated Balance Sheets.

The fair value of financial assets measured on a recurring basis is as follows (in thousands):

 

 

 

 

Short-term and long-term investments

All of the Company's short-term and long-term investments are classified as available-for-sale. Available-for-sale debt securities with maturities greater than twelve months are classified as long-term investments when they are not intended for use in current operations. Investments in available-for-sale securities are reported at fair value with unrecognized gains (losses), net of tax, as a component of accumulated other comprehensive income on the Consolidated Balance Sheets. The Company had money market funds of $4.4 million and $3.9 million at March 31, 2015 and March 31, 2014, respectively, included in cash and cash equivalents on the Consolidated Balance Sheets. The Company monitors its investments for impairment periodically and records appropriate reductions in carrying values when the declines are determined to be other-than-temporary.

---

 

The following table summarizes the Company's available-for-sale investments:

 

 

 

 

The Company's investment portfolio consists of both corporate and governmental securities that have a maximum maturity of three years. All unrealized losses are due to changes in interest rates and bond yields. The Company has the ability to realize the full value of all these investments upon maturity.

---

 

At March 31, 2015, the deferred tax liability related to unrecognized gains and losses on short-term and long-term investments was $11,000.  At March 31, 2014, the deferred tax liability related to unrecognized gains and losses on short-term and long-term investments was $11,000.  

As of March 31, 2015, contractual maturities of the Company's available-for-sale non-equity investments were as follows:

 

 

 

 

NOTE 6—COMMITMENTS AND CONTINGENCIES

Operating leases

The Company leases office space and equipment under noncancelable operating leases with various expiration dates through August 2017. Rent expense for the years ended March 31, 2015,  2014 and 2013 was $354,000,  $368,000 and $373,000, respectively. The terms of the facility leases provide for rental payments on a graduated scale. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid.

Future minimum lease payments under noncancelable operating leases with remaining lease terms in excess of one year at March 31, 2015 are as follows:

 

 

Royalty obligations

The Company has license agreements that require it to pay royalties on the sale of products using the licensed technology. Royalty expense for the years ended March 31, 2015,  2014 and 2013 was $53,000, $59,000 and $65,000, respectively, and was included within cost of revenues.

---

 

Indemnification obligations

The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold and certain intellectual property rights. In each of these circumstances, payment by the Company is conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party's claims. Further, the Company's obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments made by it under these agreements.

It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of the Company's obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material effect on its business, financial condition, cash flows or results of operations. The Company believes that if it were to incur a loss in any of these matters, such loss should not have a material effect on its business, financial condition, cash flows or results of operations.

Product warranties

The Company warrants its products to be free of defects generally for a period of three years. The Company estimates its warranty costs based on historical warranty claim experience and includes such costs in cost of revenues. Warranty costs were not significant for the years ended March 31, 2015,  2014 or 2013.

Legal proceedings

In March 2011, Cypress Semiconductor Corporation, a semiconductor manufacturer, filed a lawsuit against the Company in the United States District Court for the District of Minnesota alleging that the Company’s products, including its SigmaDDR and SigmaQuad families of Very Fast SRAMs, infringe five patents held by Cypress.  The complaint sought unspecified damages for past infringement and a permanent injunction against future infringement.

On June 10, 2011, Cypress filed a complaint against the Company with the United States International Trade Commission (the “ITC”).  The ITC complaint, as subsequently amended, alleged infringement by the Company of three of the five patents involved in the District Court case and one additional patent and also alleged infringement by three of the Company’s distributors and 11 of its customers who allegedly incorporate the Company’s SRAMs in their products.  The ITC complaint sought a limited exclusion order excluding the allegedly infringing SRAMs, and products containing them, from entry into the United States and permanent orders directing the Company and the other respondents to cease and desist from selling or distributing such products in the United States.  On July 21, 2011, the ITC formally instituted an investigation in response to Cypress’s complaint.   On June 7, 2013, the ITC announced that the full Commission had affirmed the determination of Chief Administrative Judge Charles E. Bullock that GSI’s SRAM devices, and products containing them, do not infringe the Cypress patents and that Cypress had failed to establish existence of a domestic industry that practices the patents.  Moreover, the Commission reversed a portion of Judge Bullock’s determination with respect to the validity of the patents, finding the asserted claims of one of the patents to have been anticipated by prior art and, therefore, invalid.  The Commission ordered the investigation terminated, and Cypress did not appeal the ruling.

The Minnesota District Court case had been stayed pending the conclusion of the ITC proceeding. Following the termination of the ITC investigation, the stay was lifted.  On May 1, 2013, Cypress filed an additional lawsuit in the United States District Court for the Northern District of California alleging infringement by our products of five 

---

 

additional Cypress patents.  Like the Minnesota case, the complaint in the California lawsuit sought unspecified damages for past infringement and a permanent injunction against future infringement.  The Company filed answers in both cases denying liability and asserting affirmative defenses.  On August 7, 2013, the parties stipulated that the claims in the Minnesota case with respect to three of the asserted patents would be dismissed without prejudice and that the claims with respect to the remaining two patents would be transferred to the Northern District of California and consolidated with the pending California case.  On August 20, 2013, the Court in the California case ordered the cases consolidated.

The Company did not record any loss contingency during fiscal 2013, fiscal 2014 or fiscal 2015 in connection with these legal proceedings as the Company was unable to predict their outcome and could not estimate the likelihood or potential dollar amount of any adverse results.

Subsequent to March 31, 2015, the Company and Cypress entered into a settlement agreement resolving the patent infringement litigation and another lawsuit then pending in the same court in which the Company alleged that Cypress had violated federal and state antitrust laws.  See Note 12.

NOTE 7—COMMON STOCK

The Company's Certificate of Incorporation, as amended, authorizes the Company to issue 150,000,000 shares of $0.001 par value common stock.

On July 9, 2014, the Company announced that it had commenced a modified “Dutch auction” self-tender offer to repurchase for cash shares of its common stock for an aggregate purchase price of up to $25 million.  Under the terms of the tender offer, the Company’s stockholders had the opportunity to tender some or all of their shares at a price within the range of $6.50 to $6.70 per share.

The tender offer expired on August 6, 2014.  The Company accepted for purchase and retirement an aggregate of 3,846,153 shares of its common stock at a final purchase price of $6.50 per share, for an aggregate cost of approximately $25 million, excluding fees and expenses related to the tender offer.  A total of 10,466,830 shares were properly tendered and not properly withdrawn at a price of $6.50 per share. Since the offer was oversubscribed, the number of shares that the Company accepted for purchase from tendering stockholders was prorated, based upon the proration procedures described in the offer to purchase (other than shares tendered by “odd lot” holders, which were not subject to proration and were accepted in full).

The aggregate number of shares purchased and retired by the Company in the tender offer represented approximately 14.0 percent of its issued and outstanding shares of common stock as of August 8, 2014.  Following settlement of the tender offer, the Company had approximately 23.7 million shares of its common stock outstanding.

The Company’s board of directors has authorized the repurchase, at management's discretion, of shares its common stock. Under the repurchase program, the Company may repurchase shares from time to time on the open market or in private transactions. The specific timing and amount of the repurchases will be dependent on market conditions, securities law limitations and other factors. The repurchase program may be suspended or terminated at any time without prior notice.  Through March 31, 2015,  including the shares purchased in the modified “Dutch Auction”  self-tender offer, the Company has repurchased and retired a total of 8,728,532 shares at an average cost of $5.33 per share for a total cost of $46.5 million. At March 31, 2015, management was authorized to repurchase additional shares with a value of up to $8.5 million under the repurchase program.

NOTE 8—STOCK- BASED COMPENSATION

The 2000 Stock Option Plan

In February 2001, the Company adopted the 2000 Stock Option Plan (the "2000 Plan"). The 2000 Plan provided for the granting of stock options and stock purchase rights to employees, consultants and directors of the Company. Options granted under the 2000 Plan could be either incentive stock options ("ISOs") or nonstatutory stock options ("NSOs").  In December 2006, the Company's board of directors authorized an additional 500,000 shares of the Company's common stock to be reserved for issuance under the 2000 Plan. As of March 31, 2008, the Company had reserved 3,500,000 shares of common stock for issuance under the 2000 Plan.

Options under the 2000 Plan could be granted for periods of up to ten years. However, in the case of ISOs granted to an optionee who, at the time the option was granted, owned stock representing more than 10% of the voting power of all classes of stock of the Company, the maximum term of an option was five years from the date of grant. The exercise price of an ISO or NSO could not be less than 100% and 85% of the estimated fair value of the shares as determined by the board of directors on the date of grant, respectively.  However the exercise price of an ISO or NSO granted to a 10% or greater stockholder could not be less than 110% of the estimated fair value of the shares on the date of grant.

The 2007 Equity Incentive Plan

In January 2007, the Company's board of directors approved the 2007 Equity Incentive Plan, (the "Equity Plan"), which was subsequently approved by the Company's stockholders in March 2007. A total of 3,000,000 shares of common stock were authorized and reserved for issuance under the Equity Plan. This reserve automatically increases on April 1 of each year through 2017 by an amount equal to the smaller of (a) five percent of the number of shares of common stock issued and outstanding on the immediately preceding March 31, or (b) a lesser amount determined by the board of directors.  Appropriate adjustments will be made in the number of authorized shares and other numerical limits in the Equity Plan and in outstanding awards to prevent dilution or enlargement of participants' rights in the event of a stock split or other change in the Company's capital structure. Shares subject to awards which expire or are cancelled or forfeited will again become available for issuance under the Equity Plan. The shares available will not be reduced by awards settled in cash or by shares withheld to satisfy tax withholding obligations. Only the net number of shares issued upon the exercise of stock appreciation rights or options exercised by means of a net exercise or by tender of previously owned shares will be deducted from the shares available under the Equity Plan.

To enable compensation provided in connection with certain types of awards intended to qualify as “performance-based” within the meaning of Section 162(m) of the Internal Revenue Code, the Equity Plan establishes limits on the maximum aggregate number of shares or dollar value for which awards may be granted to an employee in any fiscal year, as follows: 

In addition, to comply with applicable tax rules, the Equity Plan also limits the number of shares that may be issued upon the exercise of ISOs granted under the Equity Plan to 3,000,000, cumulatively increased on April 1 of each

---

 

subsequent year through 2017, by an amount equal to the smallest of (a) five percent of the number of shares of common stock issued and outstanding on the immediately preceding March 31, (b) 1,500,000 shares, or (c) a lesser amount determined by the board of directors.

Upon the adoption of the Equity Plan in March 2007, the 2000 Plan was terminated, no further options were granted under the 2000 Plan, the 535,597 shares that remained reserved for grant under the 2000 Plan were cancelled, and all subsequent grants of stock options were made pursuant to the Equity Plan.

Awards may be granted under the Equity Plan to the Company's employees, including officers, directors, or consultants or those of any present or future parent or subsidiary corporation or other affiliated entity.  To date, options granted to non-officer employees generally vest 25% on the first anniversary and subsequent anniversaries of the date of grant, while grants to officers vest in full four years after the anniversary date of the officer's employment that is closest to the date of grant.  While the Company may grant ISOs only to employees, the Company may grant NSOs, stock appreciation rights, restricted stock purchase rights or bonuses, restricted stock units, performance shares, performance units and cash-based awards or other stock-based awards to any eligible participant. Non-employee director awards may be granted only to members of the Company's board of directors who, at the time of grant, are not employees. Deferred compensation awards may be granted only to officers, directors and selected members of management or highly compensated employees.

Only members of the board of directors who are not employees at the time of grant are eligible to participate in the nonemployee director awards component of the Equity Plan. The board or the compensation committee shall set the amount and type of nonemployee director awards to be awarded on a periodic, non-discriminatory basis. Nonemployee director awards may be granted in the form of NSOs, stock appreciation rights, restricted stock awards and restricted stock unit awards. Subject to adjustment for changes in the Company's capital structure, no nonemployee director may be awarded, in any fiscal year, one or more nonemployee director awards for more than 2,000 shares. However, the annual limit may be increased by the following additions: (i) an additional 10,000 shares in the fiscal year in which the nonemployee director is first appointed or elected to the board, (ii) an additional 2,000 shares in any fiscal year in which the nonemployee director is serving as the chairman or lead director of the board, (iii) an additional 1,000 shares in any fiscal year for each committee of the board on which the nonemployee director is then serving other than as chairman of the committee, and (iv) an additional 2,000 shares in any fiscal year for each committee of the board on which the nonemployee director is then serving as chairman of the committee.

In the event of a change in control as described in the Equity Plan, the acquiring or successor entity may assume or continue all or any awards outstanding under the Equity Plan or substitute substantially equivalent awards. Any awards which are not assumed or continued in connection with a change in control or exercised or settled prior to the change in control will terminate effective as of the time of the change in control. The administrator may provide for the acceleration of vesting of any or all outstanding awards upon such terms and to such extent as it determines, except that the vesting of all nonemployee director awards will automatically be accelerated in full. The Equity Plan also authorizes the administrator, in its discretion and without the consent of any participant, to cancel each or any outstanding award denominated in shares upon a change in control in exchange for a payment to the participant with respect to each vested share subject to the cancelled award of an amount equal to the excess of the consideration to be paid per share of common stock in the change in control transaction over the exercise price per share, if any, under the award.

The 2007 Employee Stock Purchase Plan

In January 2007, the board of directors approved the 2007 Employee Stock Purchase Plan (the "2007 Purchase Plan") which was subsequently approved by the Company's stockholders in March 2007. A total of 500,000 shares of the Company's common stock was authorized and reserved for sale under the 2007 Purchase Plan. In addition, the

---

 

2007 Purchase Plan provides for an automatic annual increase in the number of shares available for issuance under the plan on April 1 of each year beginning in 2008 and continuing through and including April 1, 2017 equal to the lesser of (1) one percent of the number of issued and outstanding shares of common stock on the immediately preceding March 31, (2) 250,000 shares or (3) a number of shares as the board of directors may determine. Appropriate adjustments will be made in the number of authorized shares and in outstanding purchase rights to prevent dilution or enlargement of participants' rights in the event of a stock split or other change in our capital structure. Shares subject to purchase rights which expire or are canceled will again become available for issuance under the 2007 Purchase Plan.

The Company's employees and employees of any parent or subsidiary corporation designated by the administrator will be eligible to participate in the 2007 Purchase Plan if they are customarily employed by us for more than 20 hours per week and more than five months in any calendar year. However, an employee may not be granted a right to purchase stock under the 2007 Purchase Plan if: (1) the employee immediately after such grant would own stock possessing 5% or more of the total combined voting power or value of all classes of our capital stock or of any parent or subsidiary corporation, or (2) the employee's rights to purchase stock under all of our employee stock purchase plans would accrue at a rate that exceeds $25,000 in value for each calendar year of participation in such plans.

The 2007 Purchase Plan is designed to be implemented through a series of sequential offering periods, generally six (6) months in duration beginning on the first trading day on or after May 1 and November 1 of each year. The administrator is authorized to establish additional or alternative sequential or overlapping offering periods and offering periods having a different duration or different starting or ending dates, provided that no offering period may have a duration exceeding 27 months.

Amounts accumulated for each participant under the 2007 Purchase Plan are used to purchase shares of the Company's common stock at the end of each offering period at a price generally equal to 85% of the lower of the fair market value of our common stock at the beginning of an offering period or at the end of the offering period. Prior to commencement of an offering period, the administrator is authorized to reduce, but not increase, this purchase price discount for that offering period, or, under circumstances described in the 2007 Purchase Plan, during that offering period. The maximum number of shares a participant may purchase in any six-month offering period is the lesser of (i) that number of shares determined by multiplying (x) 1,000 shares by (y) the number of months (rounded to the nearest whole month) in the offering period and rounding to the nearest whole share or (ii) that number of whole shares determined by dividing (x) the product of $2,083.33 and the number of months (rounded to the nearest whole month) in the offering period and rounding to the nearest whole dollar by (y) the fair market value of a share of our common stock at the beginning of the offering period. Prior to the beginning of any offering period, the administrator may alter the maximum number of shares that may be purchased by any participant during the offering period or specify a maximum aggregate number of shares that may be purchased by all participants in the offering period. If insufficient shares remain available under the plan to permit all participants to purchase the number of shares to which they would otherwise be entitled, the administrator will make a pro rata allocation of the available shares. Any amounts withheld from participants' compensation in excess of the amounts used to purchase shares will be refunded, without interest.

In the event of a change in control, an acquiring or successor corporation may assume our rights and obligations under the 2007 Purchase Plan. If the acquiring or successor corporation does not assume such rights and obligations, then the purchase date of the offering periods then in progress will be accelerated to a date prior to the change in control.

Stock-based compensation

The Company recognized $2,077,000, $2,228,000 and $2,278,000 of stock-based compensation expense for the years ended March 31, 2015,  2014 and 2013, respectively, as follows:

 

 

Stock-based compensation expense in the years ended March 31, 2015,  2014 and 2013 included $153,000,  $152,000 and $145,000, respectively, related to the Company's Employee Stock Purchase Plan.

 No tax benefit was recognized in either fiscal 2015 or fiscal 2014 due to a full valuation allowance. The Company recognized related income tax benefits of $221,000 in fiscal 2013. There were no windfall tax benefits realized from exercised stock options recognized in fiscal 2015. The reversal of previously recognized windfall tax benefits realized from exercised stock options was $33,000 in fiscal 2014.  Windfall tax benefits realized from exercised stock options were $92,000 during fiscal 2013. Compensation cost capitalized within inventory at March 31, 2015 was insignificant. As of March 31, 2015, the Company's total unrecognized compensation cost was $3.3 million, which will be recognized over the weighted average period of 1.99 years. The Company calculated the fair value of stock based awards in the periods presented using the Black-Scholes option pricing model and the following weighted average assumptions:

 

 

The weighted average fair value of options granted during the years ended March 31, 2015,  2014 and 2013 was $2.08,  $2.73 and $2.22, respectively.

Item 9A.    Controls and Procedures

Management's Evaluation of Disclosure Controls and Procedures

Based on their evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of March 31, 2015, our Chief Executive Officer and Chief Financial Officer, have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report for the purpose of ensuring that the information required to be disclosed by us in the reports we file or submit under the Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that the information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, in order to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within GSI Technology, have been detected.

Management's Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements and can only provide reasonable assurance with respect to financial statement preparation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We assessed the effectiveness of our internal control over financial reporting as of March 31, 2015. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control—Integrated Framework (2013). Based on our assessment using those criteria, our management (including our Chief Executive Officer and Chief Financial Officer) concluded that our internal control over financial reporting was effective as of March 31, 2015.

The effectiveness of the Company's internal control over financial reporting as of March 31, 2015 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears on page 51 of this Annual Report on Form 10-K.
