Datasheet Summary

Description

memory (SRAM) devices.

eliminating the need for high-speed bus turnaround.

all internal operations are self-timed.

Features

1Mx36 and 2Mx18 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.
Fixed 2-bit burst for read and write operations.
Clock stop support.
Two input clocks (K and K#) for address and control registering at rising edge.
