Chartered and MoSys Collaborate on 90nm High Density Memory Components

MoSys joins Chartered's NanoAccess Alliance; Silicon validation of 1T-SRAM by Q1 2004

MILPITAS and SUNNYVALE, Calif. - September 18, 2003 - Chartered Semiconductor Manufacturing (Nasdaq: CHRT and SGX-ST: Chartered), one of the world's top three dedicated semiconductor foundries, and MoSys, Inc. (Nasdaq:MOSY), the industry's leading provider of high density system-on-chip (SoC) embedded memory solutions, today announced they are porting MoSys' innovative 1T-SRAMÒ - RÔ technology to Chartered's NanoAccessÔ 90-nanometer (nm) semiconductor manufacturing process. MoSys has joined Chartered's NanoAccess Alliance solidifying the companies' ongoing collaboration, which includes validation of a 90nm test chip containing the 1T-SRAM memory technology in October 2003. Complete silicon characterization is scheduled for the first quarter of 2004.

"Our commitment to support Chartered's NanoAccess 90nm technologies extends MoSys' existing offering of high-density memory for Chartered's manufacturing processes, which currently includes silicon-validated 0.18-micron through 0.13-micron components," said Mark-Eric Jones, vice president and general manager of Intellectual Property for MoSys. "With access to our embedded memory across multiple process nodes, companies can leverage familiar, proven intellectual property building blocks to maintain consistency and reduce risk during design and manufacturing as they move to 90nm technologies for their next-generation products."

"Chip companies are moving to leading-edge process technologies for performance reasons, and this in turn drives the need for more memory to drive complex system functions. This is proving true at 0.13 micron and becomes imperative for chips at 90nm and beyond," said Kevin Meyer, vice president of worldwide marketing and services at Chartered. "High-density embedded memory solutions such as MoSys' 1T-SRAM technology enable our mutual customers to cost-effectively support more system functionality in silicon."

MoSys is an inaugural member of Chartered's NanoAccess Alliance, and joins the extensive ecosystem of industry-leading library, electronic design automation, intellectual property, and outsourced design and manufacturing services companies. The NanoAccess Alliance brings together critical system-on-chip technologies and services with Chartered's NanoAccess semiconductor manufacturing processes for 90nm and beyond. Chartered and the NanoAccess Alliance companies promote access to open design solutions that allow foundry customers more control over their leading-edge design and manufacturing options.

Mosys' patented semiconductor 1T-SRAM memory technology offers a combination of high density, low power consumption, high speed and low cost. It provides significant advantages over traditional SRAM in density, power consumption and cost that enable designers to more economically use a larger amount of memory. Instead of six transistors utilized in a traditional SRAM storage cell, each 1T-SRAM storage cell contains only one transistor and one capacitor, thus reducing the silicon required and lowering cost.

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 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 available on MoSys' website at http://www.mosys.com.
