Highest Density Monolithic Fast SRAMs on the Market
Groundbreaking 144Mbit SigmaQuad and SigmaDDR Fast SRAMs, in both Type-II and Type-II+ versions are now sampling from GSI technology. Offered in 36 different configurations, not counting speed bin and temperature variations, this family of 65nm SRAMs provides the market’s highest level of integration available for any SRAM type and includes versions that deliver 65Gb/s of raw data bandwidth and others that deliver fully random address rates as high as 500 MHz. In addition to early applications in high performance test equipment, these 144Mbit Fast SRAMs are ideal for networking applications, including 40G/100G internet routers, Ethernet switches, and 3G base stations. The family will also go into medical imaging and military signal processing systems that demand large, high transaction rate memory arrays.
The rich selection of architectures and features available in the 144Mbit product family allows system designers to find exactly the right SRAM, whether they are optimizing for high bandwidth, low latency, or high transaction rate performance
Building on experience gained while shipping 144Mbit stacked die modules since 2008, the new 144Mbit monolithic family allows GSI to deliver a better power/performance ratio and a better price/performance ratio to both current and new customers. In addition, architectural innovations in the SigmaQuad/SigmaDDR-II+ devices include On-die Termination (ODT) that improves signal integrity, reduces system cost and saves board space by eliminating any need for external termination resistors.
