GSI Technology samples 144Mbit SigmaQuad/SigmaDDR-II and II+ SRAMs

SANTA CLARA, USA: GSI Technology announced sampling of its groundbreaking 144Mbit SigmaQuad and SigmaDDR Fast SRAMs, in both Type-II and Type-II+ versions.

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.

“As of Monday we have already delivered customer samples,” said Lee-Lean Shu, CEO of GSI Technology. “And leading customers like ZTE and H3C are particularly anxious to receive additional shipments this week since they have not yet been able to get 144Mbit parts from any other vendor.”

According to David Chapman, VP of Marketing and Applications Engineering for GSI Technology, “The rich selection of architectures and features available in our 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.” Mathieu Duprez, president of MuTest, said: “GSI is the only vendor to deliver 144Mbit SRAMs to us so far. We put high value on early access to leading edge technology and are pleased to be working with GSI.”

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.

GSI Technology's 144Mbit SigmaQuad/SigmaDDR-II and SigmaQuad/SigmaDDR-II+ products are sampling now. Pricing for the GS81302D19-333 is $170.00 while the GS81302D18-167 is $145.00 in 1,000 piece quantities.
