CY7C1423BV18 - Cypress Semiconductor

CY7C1423BV18 36-Mbit DDR-II SIO SRAM 2-Word Burst Architecture

The CY7C1422BV18, CY7C1429BV18, CY7C1423BV18, and CY7C1424BV18 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 .

■ Functional Description The CY7C1422BV18, CY7C1429BV18, CY7C1423BV18, and CY7C1424BV18 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 ea.
