SRAM boasts transaction rate of 2132 million per second

Keywords:SRAM  Cypress  random transaction rate 

Cypress Semiconductor Corporation has developed what it claims is the industry's first quad data rate IV (QDR-IV) SRAM that can deliver up to 2,132 million transactions per second (MT/s)—a random transaction rate (RTR) that enables the processing of look-up tables, statistics, state counters, and scheduling functions stored in memory.

QDR-IV SRAM is capable of operating in burst-of-two or banked burst-of-two modes, which deliver the fastest clock speeds and highest RTR of all QDR SRAMs. The banked burst-of-two operating mode operates at a maximum frequency of 1,066MHz with an RTR of 2,132MT/s. The standard burst-of-two operating mode, on the other hand, can achieve a maximum frequency of 667MHz and an RTR of 1,334MT/s.

QDR-IV was developed in the QDR consortium, whose members jointly define SRAM standards to enable multiple sources and supply stability. The 144Mbit CY7C41xxKV and 72-Mbit CY7C40xxKV QDR-IV SRAMs are shipping in production quantities now, available in a 361-ball flip chip ball grid array (FCBGA) package.
