IS61QDPB44M18 - QUADP (Burst of 4) Synchronous SRAMs

Download the IS61QDPB44M18 datasheet PDF. This datasheet also covers the IS61QDPB42M36 variant, as both devices belong to the same quadp (burst of 4) synchronous srams family and are provided as variant models within a single manufacturer datasheet.

General Description

The 72Mb IS61QDPB42M36 and IS61QDPB44M18 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

  • 2M x 36 or 4M x 18.
  • On-chip delay-locked loop (DLL) for wide data valid window.
  • Separate 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.
  • 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 o.
