NexusChips to Use MoSys 1T-SRAM in Its Leading Mobile 3D Graphics
and Multimedia SoC Solutions

SUNNYVALE, Calif. & SEOUL, South Korea–(BUSINESS WIRE)–Dec. 13,
2006–MoSys, Inc. (NASDAQ: MOSY), the industry’s leading provider of
high-density system-on-chip (SoC) embedded memory solutions, and
NexusChips Co. Ltd, a leader in high-performance 3D graphics chips for
mobile handhelds, today announced a licensing agreement whereby
NexusChips will utilize MoSys 1T-SRAM technology to enable mobile
handheld applications that have not been possible with previous memory
technologies. NexusChips GiPump 3D graphics accelerators and mobile
stereoscopic display features are enabled by the dense, low-power
technology offered in the MoSys 1T-SRAM. The NexusChips application in
consumer mobile expands upon MoSys’ application in home entertainment
and mobile multimedia.

“The power, density, and performance capabilities of the MoSys
1T-SRAM enables NexusChips to offer leading features including
stereoscopic 3D graphics with world-beating performance at more than
20 frames/second of sustained frame rate,” said HK Kim, president and
CEO of NexusChips. “By working with MoSys, NexusChips can offer
product features and performance not possible using conventional
embedded memory technology. The NexusChips GiPump has been verified
and selected by major mobile players.”

“We are pleased to have such a leading developer of mobile 3D
graphics solutions among those licensing the MoSys technology,” said
Chet Silvestri, chief executive officer of MoSys. “The NexusChips
application is indicative of a leading trend in mobile handheld
devices, in which sophisticated and powerful 3D graphics are utilized
in high-volume mobile telephones and gaming devices. We are pleased to
help enable this trend.”

About MoSys, Inc.

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
100 million chips incorporating 1T-SRAM embedded memory technologies,
demonstrating excellent manufacturability in a wide range of silicon
processes and applications. MoSys is headquartered at 755 N. Mathilda
Avenue, Sunnyvale, California 94085. More information is available on
