SUNNYVALE, Calif. & SANTA CLARA, Calif. -- 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.
