2004–MoSys, Inc. (NASDAQ:MOSY), the industry’s leading provider of
high density SoC embedded memory solutions, and SigmaTel, Inc.
(NASDAQ:STGL) a provider of application-specific mixed-signal
integrated circuits (ICs) for the consumer electronics and computing
markets, today announced a long-term agreement enabling SigmaTel, Inc.
to license MoSys’ 1T-SRAM(R) embedded memory technologies to enhanced
future mixed-signal product features and benefits.

“We selected MoSys’ 1T-SRAM technology for its consistent track
record of volume production, proven performance, low power and cost
advantages,” said Roger Whatley, CTO and vice president of engineering
at SigmaTel. “By using the MoSys high-density embedded memory
solution, we can provide our customers an efficient, high quality,
cost-effective solution for their next generation of products.”

“We are pleased that SigmaTel has chosen MoSys’ 1T-SRAM technology
for their innovative products,” noted Mark-Eric Jones, vice president
and general manager of intellectual property at MoSys. “1T-SRAM
technology can substantially reduce the die area and power as well as
improve yields. As the proportion of SoC die area occupied by memory
continues to grow, these benefits translate to dramatic advantages for
the whole SoC and, accordingly, for SigmaTel and its customers.”


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 memory, demonstrating the
excellent manufacturability of the technology in a wide range of
silicon processes and applications. MoSys is headquartered at 1020
Stewart Drive, Sunnyvale, California 94085. More information is
