IS61DDB24M18C - 72Mb DDR-II CIO SYNCHRONOUS SRAM

General Description

The 72Mb IS61DDB22M36C and IS61DDB24M18C 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.

Key Features

  • 2Mx36 and 4Mx18 configuration available.
  • Common I/O read and write ports.
  • Max. 400 MHz clock for high bandwidth.
  • 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#) for data output contro.
