3.3 V 128 K × 8 Dual-Port Static RAM


  • True dual-ported memory cells which allow simultaneous access of the same memory location
  • 128 K × 8 organization (CY7C009)
  • 0.35-micron CMOS for optimum speed/power
  • High-speed access: 15/20/25 ns
  • Low operating power
    • Active: ICC = 115 mA (typical)
    • Standby: ISB3 = 10 μA (typical)
  • Fully asynchronous operation
  • Automatic power-down

Functional Description

The CY7C009V is a low-power CMOS 64 K, 128 K × 8 dual-port static RAM. 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. The devices can be utilized as standalone 8/9-bit dual-port static RAMs or multiple devices can be combined in order to function as a 16/18-bit or wider master/slave dual-port static RAM.
