Renesas, Cypress, Infineon, Micron to Co-Develop CellularRAM Specs

4/21/2004 - The CellularRAMTM specification co-development team, including Cypress Semiconductor Corp. (NYSE:CY), Infineon Technologies (FSE/NYSE:IFX) and Micron Technology, Inc. (NYSE:MU), announced the addition of Renesas Technology Corp. to its membership. Cypress, Infineon and Micron, as individual companies, are all extremely active in the Asia market with facilities in China, India, Japan, Singapore and the Philippines. Their focus and commitment to this market is solidified with the addition of Renesas to the specification co-development. Renesas is now the first Asia-headquartered manufacturer developing a family of CellularRAM devices for next-generation mobile handsets.

CellularRAM products are a high-performance, low-power memory solution designed to meet the growing memory density and bandwidth demands of future 2.5G and 3G handset designs. In addition to offering a lower cost/bit ratio than current solutions, this new multi-sourced, multi-generation family of pseudo-static RAM (PSRAM) products features SRAM-pin compatibility, external refresh-free operation and a low-power design. CellularRAM devices are a drop-in replacement, pin-and-function-compatible, for most asynchronous low-power SRAMs used currently in cellular phone designs.

"The handset community voiced a strong need for a cost-effective, high-performance, low power solution tailored specifically to meet their unique system requirements. Renesas, recognizing the benefits CellularRAM technology brings to this marketplace, joined the CellularRAM specification co-development," said Masahiro Yamamura, executive general manager of memory business unit at Renesas Technology. "We are excited to participate in the co-development of this specification as our customers tell us CellularRAM products are their choice for mobile handset applications."

Cypress, Infineon and Micron said in a joint statement, "We are pleased to welcome Renesas to the co-development of the CellularRAM specification. We value Renesas as a broad-based semiconductor supplier and believe the addition of this major Asia-region vendor to the group strengthens global adoption of CellularRAM technology. The CellularRAM specification co-development members deliver a new memory standard with superior performance to customers with the collective benefit of the members' wide-range of market experience and innovative technology."

The purpose of this specification co-development effort is to provide customers with pin- and function-compatible products from multiple sources, based on a jointly developed specification for the CellularRAM architecture. Each member company provides system expertise and product direction, and designs and manufactures their own products using their own design and process technology.

Based on a one-transistor (1T) DRAM cell, CellularRAM products provide significant advances over traditional SRAM and a six-transistor (6T) SRAM cell, leveraging the technology and reduced size of a DRAM cell. These products operate at up to 104 MHz clock rates; run at an initial latency of 39ns; and can achieve up to 208 MB/s of peak bandwidth. CellularRAM products also feature a burst read and write mode that emulates a popular Flash Burst compatible protocol with various I/O voltage options, making them ideal for multichip package (MCP) products.

MCP solutions are a growing trend for mobile applications. As CellularRAM products are ideal companion devices, the co-development continues to enable the market by designing future generations of CellularRAM products with a common bond format supporting the MCP requirements of the membersí respective customers.

Like other specification co-development members, Renesas will design their devices using their own technology and will manufacture them in their own fabrication facilities. Renesas products will be delivered to market according to the company's internal schedules. Member companies continue to work together to define the specification for the next-generation CellularRAM products.
