Description

The 36Mb IS61DDB21M36A and IS61DDB22M18A are synchronous, high-performance CMOS static random access memory (SRAM) devices. These SRAMs have a common I/O bus.

Key Features

  • 1Mx36 and 2Mx18 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.
  • 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 control.
  • Two echo clocks (CQ and CQ#) that are delivered simultaneously with data.
