Functional Description
The CYDC128B16 is a low power complementary metal oxide semiconductor (CMOS) 4k, 8k,16k x 16, and 8/16k x 8 dual-port static RAM. 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 used as standalone 16-bit dual-port static RAMs or multiple devices can be combined in order to function as a 32-bit or wider master/slave dual-port static RAM.
