Description

The 72Mb IS61DDB42M36 and IS61DDB44M18 are synchronous, high-performance CMOS static random access memory (SRAM) devices. These SRAMs have a mon I/O bus.

Key Features

  • 2M x 36 or 4M x
  • On-chip delay-locked loop (DLL) for wide data valid window
  • mon I/O read and write ports
  • Synchronous pipeline read with late write operation
  • Double data rate (DDR-II) 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 only
  • Two input clocks (C and C) for data output control
  • Two echo clocks (CQ and CQ) that are delivered simultaneously with data
