8K X 8/9 Dual-Port Static RAM With SEM, INT, BUSY

The CY7C144 and CY7C145 are high-speed CMOS 8K x 8 and 8K x 9 dual-port static RAMs. Various arbitration schemes are included on the CY7C144 5 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 CY7C144 5 CAN be utilized as a standalone 64/72-Kbit dual-port static RAM 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 Appli- cation areas include interprocessor/multiprocessor designs, Communications status buffering, and dual-port Video graphics memory.
