New SRAM Specifications - QDRII+ and DDRII+ - are Announced

Cypress Semiconductor Corp., Integrated Device Technology, Inc., NEC Electronics Corporation, Renesas Technology Corp., and Samsung Electronics Co., Ltd. has announced the release of the complete specification for Quad Data Rate II+ (QDRII+) and Double Data Rate II+ (DDRII+) SRAM (static random access memory) architectures. Operating at speeds up to 500 MHz, QDRII+ and DDRII+ products will offer improved speeds up to 50 percent faster than existing QDRII and DDRII products. The new high-performance communications memory standard has been developed for network switches, routers and other communications applications.

QDRII+ and DDRII+ products will deliver a higher bandwidth than QDRII and DDRII respectively - up to 72 Gbps, while using the same footprints and a 165-pin, FBGA (Fine-pitch Ball Gate Array) package.

The QDR and DDR families of SRAM will provide designers with a complete memory solution for almost any network application. QDRII+ devices will have two ports operating independently at twice the selected clock rate, allowing a transfer of four data words in a single clock cycle. The DDRII+ devices will allow double data rate transfers over a common I/O data bus.
