QDR SRAM Hits 550 MHz; While Reducing Power Consumption by 50 Percent
Page 1 of 1
New Quad Data Rate (QDR) and Double Data Rate (DDR) SRAMs at 36 Mbit and 18 Mbit densities are now the latest members of the 65nm SRAM family from Cypress Semiconductor. The new memories complete the broad portfolio of 65nm synchronous SRAMs, which includes densities up to 144 Mbit and speeds up to 550 MHz. Cypress’s patented process technology reduces power consumption up to 50% compared with 90nm SRAMs, enabling the new wave of “green” networking infrastructure applications.
The new devices are form, fit and function compatible upgrades for the large installed base of 90nm QDRII/QDRII+ SRAMs (estimated at well over 60 million units), and are fully compliant with the QDR Consortium specifications. This compatibility enables designers of existing products to easily upgrade system performance without requiring board redesign. The 65nm SRAMs are suitable for networking applications, including 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. The QDRII+ and DDRII+ devices feature On-Die Termination (ODT), which improves signal integrity, reduces system cost, and saves board space by eliminating external termination resistors.
