Industry’s fastest QDR SRAM

18 January 2011

Cypress’ QDR and DDR SRAMs at 36Mbit and 18Mbit densities are the latest in its 65nm SRAM family.

The new memories complete the industry’s broadest portfolio of 65nm synchronous SRAMs, which includes densities up to 144Mbit and speeds up to 550 MHz.

Cypress’s patented process technology reduces power consumption by 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 ideal 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.

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.

“As the leader in SRAMs, we aim to provide the broadest portfolio of high-performance SRAM products, giving our customers the ability to offer a wide range of price/performance points in their markets,” said Dave Kranzler, Vice President of synchronous SRAM products at Cypress.

“Cypress has already shipped over a million 65nm SRAMs to over 150 customers worldwide, and we have established ourselves as the leader in the high performance SRAM category,” added Kranzler.

Cypress’s portfolio of SRAMs includes leaded and lead-free packaging; commercial, industrial and military options; numerous interface configurations; and a wide range of performance options. Cypress also works with customers to develop solutions for specific application requirements.

The 36Mbit CY712xxKV18 and 18-Mbit CY7C11xxKV18 are available in production quantities now from Cypress and its distribution partners. Each device is available in multiple configurations based on I/O width (x18 or x36), burst length (B4 or B2) and latency (1.5ns, 2.0ns or 2.5ns).
