IS61QDB44M18 - QUAD (Burst of 4) Synchronous SRAMs
The 72Mb IS61QDB42M36 and IS61QDB44M18 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.
The rising edge of K clock initiates the read/write operation, and all internal operations are
IS61QDB44M18 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 an
