... Functional Description The CY7C138V/144V/006V/007V and CY7C139V/145V/ 016V/017V are low-power CMOS 4K, 8K, 16K, and 32K x8/9 dual-port static RAMs. Various arbitration schemes are includ the devices to handle situations when multiple proces- sors access the same piece of data. Two ports are provided, permitting independent, asynchronous access for reads and writes to any location in memory ...
