SUNNYVALE, Calif., Jul 23, 2010 (BUSINESS WIRE) —

MoSys,
Inc.
(NASDAQ: MOSY), a leading provider of serial chip-to-chip
communications solutions that deliver unparalleled bandwidth performance
for next generation networking systems and advanced system-on-chip (SoC)
designs, has successfully taped out its Bandwidth Engine(TM) integrated
circuit (IC). This first member of the MoSys Bandwidth Engine family of
advanced system solutions will combine MoSys’ patented 1T-SRAM(R)
high-density embedded memory with its ultra high-speed 10 Gigabits per
second (Gbps) SerDes interface (I/O) technology and an arithmetic logic
unit (ALU).

MoSys expects its Bandwidth Engine to enable up to four times the
throughput, two to four times the density, up to 40 percent lower power
and deliver a system cost savings of up to 50 percent, compared with
today’s alternative solutions. MoSys is targeting to deliver first
samples in late 2010, with production quantities available in 2011.

“The tape-out of our first Bandwidth Engine IC is a major milestone in
MoSys’ transition to a fabless semiconductor company, and I want to
congratulate our engineering team on this magnificent accomplishment. We
have several prospective customers lined up in the high speed networking
and storage markets, and this tape-out is a key first step in bringing
the first Bandwidth Engine product to market,” said Len Perham,
President and CEO of MoSys. “We believe that the market for our
Bandwidth Engine family of ICs will be substantial and provide a strong
foundation for long-term growth and value creation at MoSys.”

For the past several years, processor performance in applications, such
as computing and networking, has continued to nearly double every 18
months. During the same period, the performance of today’s system memory
technology has not kept pace, creating a significant barrier to
improving overall equipment performance. The Bandwidth Engine family of
ICs represents a breakthrough for next-generation networking systems.
Combining the high-speed random access of a 1T-SRAM memory core with 16
serial I/O lanes operating at 10 Gbps will enable a Bandwidth Engine
device to provide up to two billion accesses per second, which is more
than twice the performance of designs utilizing conventional memory
technology. To further boost system performance, the on-chip ALU will
allow macro functions to be performed within the Bandwidth Engine,
reducing iterations between the other packet processing ICs and the
Bandwidth Engine device, the net result of which will be less intra-card
electrical traffic, fewer pins, lower power, higher speed and an
improved and reduced system cost.
