Functional Description

The CY7C144AV and CY7C006AV are low-power CMOS 8 K / 16 K × 8 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-bit dual-port static RAMs or multiple devices can be combined in order to function as a 16-bit or wider master/slave dual-port static RAM.
