Abstract
An apparatus used in a self-referenced read of a memory bit cell includes circuitry including a plurality of transistors that includes an NMOS-follower transistor for applying a read voltage to a first end of the bit cell. An offset current is applied by an offset current transistor. A transmission gate allows for isolation of a capacitor used to store a sample voltage corresponding to the read voltage applied across the memory bit cell.
