UM2149 - 1K x 4 High Speed NMOS SRAM

Datasheet Summary

Description

The UMC UM2149 is a 4096-8it Static Random Access Memory organized 1024 words by 4 bits and is fabricated using UMC's new N-channel Silicon-Gate HMOS technology.

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

Features

45 ns maximum address access.
Fully static operation: No clocks or strobes required.
Fast chip select access time: 20ns max.
Identical cycle and access times.
Single +5V supply.
Industry standard 2114 pinout.
Totally TTL compatible: All inputs and outputs.
Common data input and outputs Ii High density 18-pin package.
Three-state output General.
