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 CY7C12661KV18 , 9-bit words CY7C12771KV18 , 18-bit words CY7C12681KV18 , or 36-bit words CY7C12701KV18 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. These devices are down bonded from the 65 nm 72 M QDRII+/DDRII+ devices and hence have the same IDD/ISB1 values and the same JTAG ID code as the equivalent 72 M device options. For details refer to the application note AN53189, 65 nm Technology InterimQDRII+/DDRII+ SRAM device family description.
