That eliminates the bus-turnaround dead cycles you get with common I/O SRAM, so back-to-back read-write throughput stays at the full 300 MHz rate. Organized as 2M x 36, it targets high-bandwidth data buffers in network switches, line cards, and test equipment where latency consistency matters more than raw density.
The part ships in a 165-ball FBGA (15x17 mm body), surface-mount only.
Cypress has not published an official drop-in replacement for this specific density and speed grade. A redesign to a current QDR II+ or QDR IV SRAM in a similar FBGA footprint is the typical path, but pin compatibility must be verified against the target package and timing specification.
The part is supplied in a 165-ball FBGA (15x17 mm body) on Tray. It is surface-mount only.
It is a synchronous SRAM using the QDR II architecture — separate read and write ports with double-data-rate transfers at 300 MHz.
