IS61DDB251236A, IS61DDB21M18A Datasheet - Integrated Silicon Solution

IS61DDB251236A 18Mb DDR-II (Burst 2) CIO SYNCHRONOUS SRAM

The 18Mb IS61DDB251236A and IS61DDB21M18A are synchronous, high-performance CMOS static random access memory (SRAM) devices. These SRAMs have a common I/O bus. The rising edge of K clock initiates the read/write operation, and all internal operations are self-timed. Refer to the Timing Reference Dia.

IS61DDB251236A Features

* 512Kx36 and 1Mx18 configuration available.

* On-chip delay-locked loop (DLL) for wide data valid window.

* Common I/O read and write ports.

* Synchronous pipeline read with self-timed late write operation.

* Double Data Rate (DDR) interface for read and write input ports.
