3.3V 4K/8K/16K/32K X 8/9 Dual-Port Static RAM

The CY7C138AV CY7C144AV CY7C006AV CY7C007AV and CY7C139AV CY7C145AV CY7C016AV CY7C017AV are low-power CMOS 4K, 8K, 16K, and 32K x8/9 dual-port static RAMs. Various arbitration schemes are included on the devices to handle situations when multiple processors access the same piece of data. Two ports are provided, permitting independent, asynchronous access for reads and writes to any location in memory. The devices CAN be utilized as standalone 8/9-bit dual-port static RAMs or multiple devices CAN be combined in order to function as a 16/18-bit or wider master/slave dual-port static RAM. An M/S pin is provided for implementing 16/18-bit or wider memory applications without the need for separate master and slave devices or additional Discrete Logic Application areas include interprocessor/multiprocessor designs, Communications status buffering, and dual-port Video graphics memory.
