The 36Mb IS61DDP2B21M36C/C1/C2 and IS61DDP2B22M18C/C1/C2 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. Refer to the Timing Reference Diagram for Truth Table for a description of the basic operations of these DDR-IIP (Burst of 2) CIO SRAMs. Read and write addresses are registered on alternating rising edges of the K clock. Reads and writes are performed in double data rate. The following are registered internally on the rising edge of the K clock:
