The DDR-II+ consists of an SRAM core with advanced synchronous peripheral circuitry. Addresses for read and write are latched on alternate rising edges of the input K clock. Write data is registered on the rising edges of both K and K. Read data is driven on the rising edges of K and K. Each address location is associated with two 8-bit words CY7C1566V18 , 9-bit words CY7C1577V18 , 18-bit words CY7C1568V18 , or 36-bit words CY7C1570V18 that burst sequentially into or out of the device. Asynchronous inputs include an output impedance matching input ZQ . Synchronous data outputs Q, sharing the same physical pins as the data inputs, D are tightly matched to the two output echo clocks CQ/CQ, eliminating the need for separately capturing data from each individual DDR SRAM in the system design. All synchronous inputs pass through input registers controlled by the K or K input clocks. All data outputs pass through output registers controlled by the K or K input clocks. Writes are conducted with on-chip synchronous self-timed write circuitry.
