Chartered’s Customers Benefit from Proven IP With Highest Density
of Any Third-Party, Open Offering of Embedded High-Performance RAM


MoSys, Inc. (Nasdaq:MOSY), the industry’s leading provider of
advanced high density embedded memory solutions, and Chartered
Semiconductor Manufacturing (Nasdaq:CHRT) (SGX:CHARTERED), one of the
world’s top three dedicated semiconductor foundries, today announced
the silicon validation of MoSys 1T-SRAM-Q(TM) (Quad density) embedded
memory technology on Chartered’s 0.13-micron industry-standard logic
process. Their joint efforts have produced functional silicon devices
and already resulted in new design engagements with mutual customers.
The final phases of qualification are underway with full
characterization data to be available by the end of the third quarter

With a complete macro density of approximately 1.2-square
millimeters per megabit, 1T-SRAM-Q technology enables designers to
embed even larger high-performance memories in their system-on-chip
(SoC) designs. 1T-SRAM-Q technology incorporates MoSys’ proprietary
Transparent Error Correction(TM) (TEC(TM)) technology delivering the
additional benefits of improved yield and reliability with elimination
of laser repair and soft error concerns.

“Chartered’s 0.13 silicon verification of 1T-SRAM-Q memory
demonstrates MoSys’ continued commitment to develop the best-in-class
memory technology,” commented Dr. Fu-Chieh Hsu, president and CEO of
MoSys. “Now, SoC designers can integrate over 100 megabits of
high-performance embedded memory in 0.13-micron designs.”

1T-SRAM-Q memory is based on MoSys’ patented Folded Area
Capacitor(TM) (FAC (TM)) technology to reduce bit cell size by
literally folding the bit cell gate oxide capacitor vertically down
the STI sidewall, thus dramatically reducing the horizontal area. This
results in typical bit cell sizes of 0.57 square microns at the
0.13-micron process node.

“The memory requirements of our customers are increasing over time
and with each technology node. By coupling MoSys’ high-density
embedded memory technologies with our production-proven 0.13-micron
process, we’re giving designers more choices,” said Kevin Meyer, vice
president of worldwide marketing and services at Chartered. “With
access to these world-class solutions, our customers can reduce the
risks of implementing leading-edge, memory-intensive SoCs and still
target the highest possible yields.”

The 1T-SRAM-Q validation effort is an extension of the ongoing
collaboration by the two companies to offer optimized high-density
memory solutions on multiple technology generations and products.
MoSys and Chartered have already successfully qualified MoSys’
1T-SRAM-R high-density memory solution on Chartered’s 0.18-micron and
0.13-micron process technologies. The companies are in the process of
qualifying the 1T-SRAM-R technology on the 90nm process platform
jointly developed by Chartered and IBM.

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 it ideal for
embedding large memories in System on Chip (SoC) designs. MoSys’
licensees have shipped more than 50 million chips incorporating
1T-SRAM embedded memories, demonstrating the excellent
manufacturability of the technology in a wide range of silicon
processes and applications. MoSys is headquartered at 1020 Stewart
Drive, Sunnyvale, Calif. 94085. More information is available on
