DDR-II SIO | Cypress Semiconductor


The DDRII SIO SRAMs are similar to DDRII CIO SRAMs but they include two separate ports: the read port and the write port to access the memory array. The read port has data outputs to support read operation and the write port has data inputs to support write operation. The DDR II SIO SRAM completely eliminates the need to "turnaround" the data bus required with common I/O devices.
