SUNNYVALE, Calif., Jun 13, 2005 (BUSINESS WIRE) — MoSys, Inc. (NASDAQ: MOSY), the industry’s leading
provider of high-density system-on-chip (SoC) embedded memory
solutions announced today the availability of its 1T-SRAM(R) memory
compiler for standard 0.13-micron CMOS logic processes. The compiler
targets processes from TSMC, Chartered, SMIC and UMC. The MoSys memory
compiler is a web-accessible tool that automatically generates a wide
variety of design scenarios for MoSys’ 1T-SRAM memory, thereby
enabling SoC designers to efficiently evaluate different memory
configurations for their designs.

Available in July through the MoSys web site
(https://dev-mosys-web-04-19.pantheonsite.io), the 0.13-micron compiler gives SoC design
engineers complete control when assessing various options and benefits
of implementing 1T-SRAM memory technology in their SoC deigns. The
compiler provides front-end design information, such as datasheets,
simulation models and timing models for synthesis. It also allows SoC
designers to include specific 1T-SRAM macro instances in their designs
by generating place and route views and specifications for memory
sizes, configurations, power, speed and temperature ranges. With this
information on hand, all of the views required for simulation,
synthesis, floor-planning and place and route of an SoC design are
generated, allowing design engineers to quickly explore numerous “what
if” scenarios. Upon customer licensing of the specified 1T-SRAM macro
design, MoSys delivers the final GDSII database for customer tape out.

The MoSys 1T-SRAM compiler is targeted for both high speed and low
power designs. When high speed options are specified, the compiler can
produce macros capable of running up to 266 MHz with bus widths from
32 bits up to 256 bits wide. High speed macro sizes range from 1/2
Megabit to 4 Megabits. The low power options generate macros capable
of achieving standby power of less than 80 micro Amps per Megabit,
with clock frequencies up to 133 MHz and bus widths of 32 bits or 64
bits wide. Low power macro sizes range from 1/2 Megabit to 4 Megabits.

“We are delighted to enable and accelerate our customers’ embedded
memory SoC designs on aggressive process geometries,” stated Karen
Lamar, vice president of sales and marketing for MoSys. “MoSys’ new
1T-SRAM compiler is an effective tool to help SoC designers ensure
that they are generating the most optimized designs and making the
best embedded memory technology selections for their product mix. We
strive to make the process of integrating MoSys’ technology into new
SoCs as efficient as possible.”

With the introduction of the 0.13-micron 1T-SRAM compiler, MoSys
now offers customers a wide choice of options in design methodologies
that include compiled, full custom and CLASSIC pre-configured memory
macros. The MoSys 0.13 micron 1T-SRAM Compiler front-views generator
is available now. The Compiler back-end optimizer is scheduled for
release in the fourth quarter of 2005.

“The availability of MoSys’ 1T-SRAM compilers, which are
parametrically coupled with the CLASSIC macros product family, is an
invaluable tool for MoSys’ customers. The SoC design process is
greatly facilitated by use of 1T-SRAM compilers, which allow for
specification optimization, resulting in a quick turn drop-in embedded
SRAM memory solution. It’s a big cost and time savings for any
semiconductor designer,” said Rich Wawrzyniak, senior ASICs & SoC
analyst with Semico Research.

ABOUT MOSYS

Founded in 1991, MoSys (NASDAQ: MOSY), develops, licenses and
markets innovative memory technologies for semiconductors. MoSys’
patented 1T-SRAM technologies offer a combination of high density, low
power consumption, high speed and low cost unmatched by other
available memory technologies. The single transistor bit cell used in
1T-SRAM memory results in the technology achieving much higher density
than traditional four or six transistor SRAMs while using the same
standard logic manufacturing processes. 1T-SRAM technologies also
offer the familiar, refresh-free interface and high performance for
random address access cycles associated with traditional SRAMs. In
addition, these technologies can reduce operating power consumption by
a factor of four compared with traditional SRAM technology,
contributing to making them ideal for embedding large memories in
System on Chip (SoC) designs. MoSys’ licensees have shipped more than
80 million chips incorporating 1T-SRAM embedded memory technologies,
demonstrating excellent manufacturability in a wide range of silicon
processes and applications. MoSys is headquartered at 1020 Stewart
Drive, Sunnyvale, California 94085. More information is available on
MoSys’ website at https://dev-mosys-web-04-19.pantheonsite.io.
