- Functional Description
The CY7C1522JV18, CY7C1529JV18, CY7C1523JV18, and CY7C1524JV18 are 1.8V Synchronous Pipelined SRAMs, equipped with Double Data Rate Separate I/O (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 eliminate the need to ‘turnaround’ the data bus required with mon I/O devices. Access to each port is acplished through a mon 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...
