Dynamic memory circuit with improved sensing scheme

Image Number 4 for United States Patent #4879692.

A dynamic type memory circuit is provided with an improved write circuit which can write a desired data signal to a memory cell in a selected column in a first mode and to a plurality of memory cells in all the columns simultaneously in a second mode. The memory circuit includes a plurality of memory cell groups, a plurality of sense amplifier groups provided for the memory cell groups, a write circuit for operatively writing an input data signal to a plurality of memory cells simultaneously in at least one memory cell groups and a plurality of independent sense amplifier activation circuits provided for the sense amplifier groups.
