IS61QDB44M18 - QUAD (Burst of 4) Synchronous SRAMs

This page provides the datasheet information for the IS61QDB44M18, a member of the IS61QDB42M36 QUAD (Burst of 4) Synchronous SRAMs family.

Datasheet Summary

Description

The 72Mb IS61QDB42M36 and IS61QDB44M18 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.

Features

2M x 36 or 4M x 18.
On-chip delay-locked loop (DLL) for wide data valid window.
Separate read and write ports with concurrent read and write operations.
Synchronous pipeline read with late write operation.
Double data rate (DDR) interface for read and write input ports.
Fixed 4-bit burst for read and write operations.
Clock stop support.
Two input clocks (K and K) for address and control registering at rising edges o.
