  MoSys Announces Renesas Electronics Support of GigaChip Interface for
  Chip-to-Chip Communications

Business Wire

SANTA CLARA, Calif. -- January 22, 2013

MoSys (NASDAQ: MOSY), a leader in semiconductor solutions that enable fast,
intelligent data access for network and communications systems, today
announced that Renesas Electronics Corporation (TSE:6723), a premier supplier
of advanced semiconductor solutions, will support the GigaChip™ Interface in
its Networking ASIC business.

The GigaChip Interface (GCI) is a scalable, high-performance, serial protocol
for chip-to-chip communications that is differentiated in efficiency and
reliability, resulting in system level benefits of reduced power, cost and
complexity. Current implementations built with compatible CEI-11G or XFI
SerDes electrical transport standards deliver up to 144Gbps of full duplex
data throughput using 16 serdes lanes when running at a 10G rate. A key
differentiator for the GCI protocol is high transport efficiency, even for
small payloads. Alternative serial interfaces are typically less than 50
percent efficient when transferring 8B and 16B data, which means that they
deliver less than half the performance at a given bandwidth. The combination
of 90 percent transport efficiency, from small to large payloads, combined
with power efficient short reach physical interconnect makes GCI ideal for
co-processor, memory, or multi-chip communication. The interface also includes
CRC error detection and automatic error recovery provisions to meet the high
reliability requirements of enterprise, service provider, and mission critical
communications and compute applications. GCI is an open, royalty-free,
interface specification designed for use with the MoSys Bandwidth Engine
family of ICs and is suitable for any chip-to-chip interconnect.

“As a leading ASIC provider to the industry, we see a major trend towards
serial chip-to-chip interconnect, which is necessary to enable systems at 100G
and beyond,” said Akira Denda, General Manager, 2^nd Industrial Network
Business Division of Renesas Electronics Corp. “We believe the GigaChip
Interface provides the reliability, performance, efficiency, and openness
needed, and we are pleased to expand our strong IP portfolio for our
networking ASIC customers.”

“Renesas Electronics is one of the world’s leading providers of
high-performance ASICs and we are pleased to have them support the GigaChip
Interface in their networking ASIC business,” said John Monson, Vice President
of Marketing for MoSys. “Through our collaboration, MoSys and Renesas will be
able to offer our mutual customers powerful solutions that combine MoSys'
Bandwidth Engine® ICs connected with ASICs from Renesas Electronics through
the GigaChip Interface.”
