Keywords:memory? SRAM? QDR? DDR? 36Mbit?

Cypress has announced its Quad Data Rate (QDR) and Double Data Rate (DDR) SRAMs at 36Mbit and 18Mbit densities, the latest members of its 65nm SRAM family. These memory chips complete its portfolio of 65nm synchronous SRAMs, which consists of densities up to 144Mbit and speeds up to 550 MHz. Cypress�s patented process technology reduces power consumption up to 50 percent compared with 90nm SRAMs, ushering a new wave of �green? networking infrastructure applications.

These devices are fully compatible for upgrades to 90nm QDRII/QDRII+ SRAMs, and are fully compliant with the QDR Consortium specifications. Such compatibility permits designers of existing products to easily upgrade system performance without requiring board redesign.

The 65nm SRAMs are suitable for networking applications, as well as core and edge routers, fixed and modular Ethernet switches, 3G basestations, and secure routers. They also enhance the performance of medical imaging and military signal-processing systems. These QDRII+ and DDRII+ devices feature On-Die Termination (ODT) that eliminates external termination resistors, while improving signal integrity, reducing cost and saving board space.

Availability: Each device is available in multiple configurations based on I/O width (x18 or x36), burst length (B4 or B2) and latency (1.5-ns, 2.0-ns or 2.5-ns).
