CY7C028 Overview
The CY7C027 and CY7C028 are low power CMOS 32 K, 64 K × 16 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.
