San Jose, Ca. --- Reflecting the importance of small footprint wireless phones and iappliances as a mainstream market, Cypress Semiconductor Corp. has joined Micron Technology Inc. and Infineon Technologies in developing the specifications for CellularRAM memory, a multi-generation family of low-power Pseudo Static RAM (PSRAM).

The new SRAM/DRAM configuration is designed to meet the growing memory and bandwidth demands of 2.5G and 3G handset designs. In addition to offering a lower cost/bit ratio than current solutions, this new type of Pseudo SRAM features SRAM-pin compatibility, external refresh-free operation and a low-power design. CellularRAM memory is a drop-in replacement for asynchronous low-power SRAM used currently in cellphone designs.

The purpose of the collaboration effort is to provide customers with pin- and function-compatible products from multiple sources, based on a jointly developed specification for CellularRAM memory. Each company will design and manufacture the products using their own design and process technology.
