Functional Description
The CY7C144AV and CY7C006AV are low-power CMOS 8K/16K x 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.

FEATUREs
■ True dual-ported memory cells which allow simultaneous access of the same memory location
■ 8K/16K x 8 organizations (CY7C144AV/006AV)
■ 0.35-micron complementary metal oxide semiconductor (CMOS) for optimum speed/power
■ High-speed access: 25 ns

   — Active: ICC = 115 mA (typical)
   — Standby: ISB3 = 10 μA (typical)
■ Fully asynchronous operation
■ Automatic power-down
■ Expandable data bus to 16 bits or more using Master/ Slave chip select when using more than one device
■ On-chip arbitration logic
