Overview

The 72Mb IS61QDPB42M36A/A1/A2 and IS61QDPB44M18A/A1/A2 are synchronous, highperformance CMOS static random access memory (SRAM) devices. These SRAMs have separate I/Os, eliminating the need for high-speed bus turnaround.

  • 2Mx36 and 4Mx18 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 late write operation.
  • Double Data Rate (DDR) interface for read and write input ports.
  • 2.5 cycle read latency.
  • 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 only.
  • Two echo clocks (CQ and CQ#) that are delivered simultaneously with data.
