CY7C144 - 8K x 9/0 Dual-Port Static RAM

Description

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.

Features

  • 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.
