UM2148 - 1K x 4 High Speed NMOS SRAM

General Description

The UMC UM2148 is a 4096-Bit Static Random Access Memory organized 1024 words by 4 bits and is fabricated using UMC's new scaled N-channel silicon.gate technology.

It is designed using fully static circuitry, therefore requiring no clock or' refreshing to operate.

Key Features

  • 45 ns maximum access time.
  • No cloS;ks or strobes required.
  • Automatic CE power down.
  • Identical cycle and access times.
  • Single+5V supply (± 10%).
  • Pinout and function compatible to SY2148.
  • Industry standard 2114 pinout.
  • Totally TTL compatible all inputs and outputs.
  • Common data input and output.
  • High density 18-pin package.
  • Three-state output General.
