IS61QDB251236A, IS61QDB21M18A, 18Mb QUAD (Burst 2) Synchronous SRAM
The and 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 self-timed.
