The and are synchronous, high- performance CMOS static random access memory (SRAM) devices.

These SRAMs have separate I/Os, eliminating the need for high-speed bus turnaround.

The rising edge of K clock initiates the read/write operation, and all internal operations are self-timed.

512Kx36 and 1Mx18 configuration available.
On-chip Delay-Locked Loop (DLL) for wide data valid window.
Separate independent read and write ports with concurrent read and write operations.
Synchronous pipeline read with EARLY write operation.
Double Data Rate (DDR) interface for read and write input ports.
2.5 Cycle read latency.
Fixed 2-bit burst for read and write operations.
Clock stop support.
Two input clocks (K and K#) for address and co.
