... Functional Description The CY7C09349AV and CY7C09359AV are high-speed 3.3V synchronous CMOS 4K and dual-port static RAMs. Two ports are provided, permitting independent, simultaneous access for reads and writes to any location in memory. isters on control, address, and data lines allow for minimal set- up and hold times. In pipelined output mode, data is registered for decreased cycle time ...
