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) (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™
SRAM family and the MoSys® Bandwidth
® 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
, 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
, 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.
