Description

The 18Mb IS61QDB251236C and IS61QDB21M18C 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.

Key Features

  • 512Kx36 and 1Mx18 configuration available.
  • On-chip Delay-Locked Loop (DLL) for wide data valid window.
  • Separate independent read and write ports with concurrent read and write operations.
  • Synchronous pipeline read with EARLY 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 output clocks (C and C#) for data output control.
  • Two echo clocks (CQ and CQ#) that are delivered simultaneously with data.
