Partnership Includes Dual-Sourcing of Sigma Quad IVe SRAM and Bandwidth Engine 2 and 3 Products

SUNNYVALE, Calif. & SANTA CLARA, Calif. — (BUSINESS WIRE) — May 19, 2014 — GSI Technology (GSI) (NASDAQ: GSIT), a leader in high-performance synchronous SRAM and low-latency DRAM products for the network and telecom markets, and MoSys (NASDAQ: MOSY), a leader in semiconductor solutions that enable fast, intelligent data access for network and communications systems, today announced a dual-sourcing product and technology partnership. The partnership includes alternate sourcing of the GSI SigmaQuad™ IVe SRAM family and the MoSys® Bandwidth Engine® 2 and 3 families of ICs. These uniquely architected, highly innovative product families provide the highest access rate solutions available for next generation networking equipment. Additionally, the companies plan to leverage the partnership and respective technologies to enable expanded roadmaps of dual-sourced high-performance memory and intelligent offload products. The leading-edge technologies available from MoSys and GSI enable higher capacity and performance, ensuring that next-generation systems can meet growing user expectations for an ever faster and more intelligent network.

This partnership provides customers with two sources of supply and a path to an expanded roadmap of high-performance parallel and serial memory products, as well as packet processor offload products, from two technology leaders.

“With strong memory expertise, backed by a deep understanding of end customer application requirements, and a commitment to technology leadership and innovation, GSI makes an excellent partner to support our Bandwidth Engine products and roadmap. We are excited to extend our portfolio with the performance-leading SigmaQuad products,” stated Len Perham, CEO for MoSys. “We believe that establishing a platform that allows for alternative sourcing of our respective high-performance solutions, complemented by an aggressive product roadmap leading to even more innovative and architecturally advanced solutions, will prove highly valuable to the market as well as to our mutual customers. We look forward to an ongoing, mutually-beneficial and cooperative relationship with GSI.”

“MoSys has taken a leadership position in developing highly efficient serial interface technology for use with its high-performance Bandwidth Engine solutions, and we are excited to add these innovative products to our memory product portfolio,” stated Lee-Lean Shu, president and CEO for GSI Technology. “The combination of technology innovation, expertise and proven execution of both GSI and MoSys creates an excellent platform for providing the capacity and performance required in our customers’ current generation of networking equipment, and establishes exciting leading-edge roadmap opportunities for next generation systems.”

GSI’s SigmaQuad IVe family of high-performance synchronous SRAM products, which includes both separate I/O quad data rate and common I/O double data rate devices, offers a variety of performance and feature options tailored to high-performance networking and telecom applications. In particular, the combination of sub-1ns random cycle time, sub-6ns read latency, and high transaction rate capability available in the IVe quad data rate devices provides a level of performance that is essential for read-modify-write applications, such as counters and statistics, in today’s 100G and 400G networking systems.

MoSys’ Bandwidth Engine ICs are designed to minimize interface pin count and maximize access and effective transaction rate for buffering, look-up and statistics operations in high-speed systems. The design includes a highly efficient serial data interface and protocol combined with large, integrated high-performance memory and offload macro functions for statistics, metering and atomic operations. The architecture maximizes transactions per second both internally and externally to increase packet processing performance while expanding system features. The Bandwidth Engine devices are designed, built and qualified for high-reliability, carrier-grade applications.
