The CY7C144 and CY7C145 are high-speed CMOS 8K x 8 and 8K x 9 dual-port static RAMs.

Various arbitration schemes are included on the CY7C144/5 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.

True Dual-Ported memory cells which allow simultaneous reads of the same memory location.
8K x 8 organization (CY7C144).
8K x 9 organization (CY7C145).
0.65-micron CMOS for optimum speed/power.
High-speed access: 15ns.
Low operating power: ICC = 160 mA (max. ).
Fully asynchronous operation.
Automatic power-down.
TTL compatible.
Master/Slave select pin allows bus width expansion to 16/18 bits or more.
