IS61DDB42M36A - 72Mb DDR-II (Burst 4) CIO SYNCHRONOUS SRAM
The 72Mb IS61DDB42M36A and IS61DDB44M18A are synchronous, high-performance CMOS static random access memory (SRAM) devices.
These SRAMs have a common I/O bus.
The rising edge of K clock initiates the read/write operation, and all internal operations are self-timed.
