IS61DDSB21M36A - 36Mb DDR-II (Burst 2) SIO SYNCHRONOUS SRAM

This page provides the datasheet information for the IS61DDSB21M36A, a member of the IS61DDSB22M18A 36Mb DDR-II (Burst 2) SIO SYNCHRONOUS SRAM family.

Datasheet Summary

Description

The 36Mb IS61DDSB21M36A and IS61DDSB22M18A are synchronous, high-performance CMOS static random access memory (SRAM) devices.

These SRAMs have a separate I/O bus.

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

Features

  • 1Mx36 and 2Mx18 configuration available.
  • On-chip delay-locked loop (DLL) for wide data valid window.
  • Seperate 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.
  • 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 edges only.
  • Two input clocks (C and C#.
