The DDR-II SIO consists of two separate ports the read port and the write port to access the memory array. The read port has data outputs to support read operations and the write port has data inputs to support write operations. The DDR-II SIO has separate data inputs and data outputs to completely eliminate the need to “turn-around” the data bus required with common IO devices. Access to each port is accomplished through a common address bus. 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 C and C if provided, or on the rising edge of K and K if C/C are not provided. Each address location is associated with two 8-bit words in the case of CY7C1422AV18, two 9-bit words in the case of CY7C1429AV18, two 18-bit words in the case of CY7C1423AV18, and two 36-bit words in the case of CY7C1424AV18 that burst sequentially into or out of the device. Asynchronous inputs include an output impedance matching input ZQ . Synchronous data outputs are tightly matched to the two output echo clocks CQ/CQ, eliminating the need to capture data separately from each individual DDR-II SIO SRAM in the system design. Output data clocks C/C enable maximum system clocking and data synchronization flexibility. 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 C or C or K or K in a single clock domain input clocks. Writes are conducted with on-chip synchronous self-timed write circuitry.

Functional Description

The CY7C1422AV18, CY7C1429AV18, CY7C1423AV18, and CY7C1424AV18 are 1.8V Synchronous Pipelined SRAMs, equipped with Double Data Rate Separate IO DDR-II SIO architecture. The DDR-II SIO consists of two separate ports the read port and the write port to access the memory array. The read port has data outputs to support read operations and the write port has data inputs to support write operations. The DDR-II SIO has separate data inputs and data outputs to completely eliminate the need to “turn-around” the data bus required with common IO devices. Access to each port is accomplished through a common address bus. 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 C and C if provided, or on the rising edge of K and K if C/C are not provided. Each address location is associated with two 8-bit words in the case of CY7C1422AV18, two 9-bit words in the case of CY7C1429AV18, two 18-bit words in the case of CY7C1423AV18, and two 36-bit words in the case of CY7C1424AV18 that burst sequentially into or out of the device.
