                 UMC TO TARGET SOC DESIGNERS' REQUIREMENTS WITH

                           NEW 1T-SRAM MEMORY STRATEGY

     Foundry licenses MoSys' 1T-SRAM technology for four process generations

SUNNYVALE, California, and HSINCHU, Taiwan-November 18, 2002-UMC (NYSE: UMC), a
world leading semiconductor foundry and MoSys, Inc (NASDAQ: MOSY) the industry's
leading provider of high density SoC embedded memory solutions, today announced
that UMC has licensed MoSys' 1T-SRAM(R) technology as part of the foundry's
enhanced IP strategy to offer SoC designers memories that are more tightly
aligned with its processes. Through this licensing agreement, UMC can now
provide customers with direct access to one of the most popular forms of memory,
1T-SRAM, in its 0.18, 0.15 and 0.13 micron, and 90 nanometer standard logic
processes. UMC's access to this technology allows the foundry to provide its own
customized versions of derivative, ultra-high density, 1T-SRAM memories.

Dr. C. T. Lee, vice president of corporate marketing at UMC said, "Memory is
vital to the success of all designs, and it is becoming increasingly more
important as it is dominating more than 50 percent of the die area in many
upcoming SoCs. As such, we want to provide memory macros that are linked as
tightly as possible to our process technologies, and those we can customize.
Besides 6T (six transistor) and trench memories, we chose 1T-SRAM memories as
alternative memories because they fit into certain application areas. And, we
decided to align with MoSys as it is one of the leading vendors of 1T-SRAM
technology."

"As UMC is one of the world's leading foundries, we are very enthusiastic that
it is adopting our technology for generating memories for its customers,"
commented Mark-Eric Jones, vice president and general manager of intellectual
property at MoSys. "The agreement allows UMC to provide design services and
support to its customers directly, while preserving continuity and stability of
business arrangements between MoSys and its licensees. In addition, it furthers
the proliferation of MoSys' 1T-SRAM embedded memory technology, including our
low standby power 1T-SRAM-M(TM) technology and our new 1T-SRAM-R(TM) offering
that incorporates Transparent Error Correction(TM) (TEC(TM)) to eliminate the
need for redundancy and laser repair while improving yield, reliability and soft
error rates. Our macros will be more adoptable by a broader audience of UMC
customers as the foundry will help accelerate availability on its specific
process technologies."

Lee continued, "Many of our customers have stated that they would like UMC to
offer its own family of embedded memory cores, as memory is becoming so
important for future SoC designs. Through this new agreement we will provide
customers the option of accessing process-aligned MoSys 1T-SRAM technology
directly through UMC."

Prior to this agreement, MoSys was already working with UMC by offering a range
of Standard 1T-SRAM memory macros that had been verified on UMC's 0.18 micron
and 0.15 micron standard



logic processes. These cores, available through MoSys, were promoted to
customers through UMC's Gold IP program.

Availability

The new customized 1T-SRAM cores under this agreement will be sold and marketed
by UMC. UMC's roadmap is to offer process-proven 0.18 micron and 0.15 micron
1T-SRAM cores to customers in Q1 2003, 0.13 micron cores in Q2 2003; and 90
nanometer cores in the second half of 2003. Pricing is available upon request.

About 1T-SRAM Technology

Since MoSys first made its 1T-SRAM memory technology available for license,
MoSys' licensees have now shipped a total of more than 45 million chips
incorporating 1T-SRAM embedded memory technology, demonstrating the excellent
manufacturability of the technology in a wide range of silicon processes and
applications.

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 technology 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, this technology can
reduce operating power consumption by a factor of four compared with traditional
SRAM technology, contributing to making it an ideal technology for embedding
large memories in System on Chip (SoC) designs. 1T-SRAM technologies are in
volume production both in SoC products at MoSys' licensees as well as in MoSys'
standalone memories. MoSys is headquartered at 1020 Stewart Drive, Sunnyvale,
California 94085. More information is available on MoSys' website at
