IS61DDSB251236C, IS61DDSB21M18C Datasheet - ISSI

IS61DDSB251236C - 18Mb DDR-II SIO SYNCHRONOUS SRAM

The 18Mb IS61DDSB251236C and IS61DDSB21M18C are synchronous, high-performance CMOS static random access memory (SRAM) devices.

These SRAMs have a separate I/O bus.

The rising edge of K clock initiates the read/write operation, and all internal operations are self-timed.
