Functional Description
The CY7C024AV/025AV/026AV and CY7C0241AV/0251AV /036AV are low-power CMOS 4K, 8K, and 16K ×16/18 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 16/18-bit dual-port static RAMs or multiple devices can be combined in order to function as a 32/36-bit or wider master/slave dual-port static RAM.
