Abstract
This specification describes a differential sense amplifier serving balanced sense lines. An imbalance in bias potential on the sense lines holds the sense amplifier in an insensitive state until just before data is to be read on the sense lines. Then a shunting device connected across the sense lines and across the inputs to the differential amplifier is activated to reduce the imbalance and thereby sensitize the differential amplifier. This shunting device is controlled by a feedback path that senses the biasing condition and shuts off the shunting device when the amplifier is in condition to perform the Read cycle.
