High current fast read scheme for crosspoint memory

Abstract:

A high current fast read scheme can enable improved read disturb without negatively impacting read performance. In one example, a fast read scheme involves applying a higher current as soon as the cell thresholds. In one example, circuitry detects the threshold event and turns on a bypass control transistor to bypass the circuitry applying the read voltage to enable a higher voltage and therefore higher current as soon as possible. The read time can thus be decreased (or at least not increased) and read disturb improved.
