IS61QDB21M18C - 18Mb QUAD Synchronous SRAM
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.
The rising edge of K clock initiates the read/write operation, and all internal operations
IS61QDB21M18C 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) inter
