Cypress Semiconductor has announced new Quad Data Rate (QDR) and Double Data Rate (DDR) SRAMs at 36-Mbit and 18-Mbit densities, the latest members of its 65-nm SRAM family. The new memories complete the company’s portfolio of 65-nm synchronous SRAMs, which includes densities up to 144Mbit and speeds up to 550 MHz.
According to Cypress, its patented process technology reduces power consumption by up to 50% compared with 90nm SRAM. The new devices are form, fit and function compatible upgrades for the large installed base of 90-nm QDRII/QDRII SRAMs (estimated at well over 60 million units), and are fully compliant with the QDR Consortium specifications.
The 65-nm SRAMs are suitable for networking applications, including core and edge routers, fixed and modular Ethernet switches, 3G basestations, and secure routers. 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.
The 36-Mbit CY712xxKV18 and 18-Mbit CY7C11xxKV18 are available in production quantities.
