Abstract:
1. A non-volatile storage system, comprising: a set of non-volatile storage elements including at least a first non-volatile storage element; and one or more control circuits in communication with the set of non-volatile storage elements, the one or more control circuits: (a) apply a first voltage to a selected word line which is associated with the at least a first non-volatile storage element, (b) apply source and p-well voltages to a source and a p-well, respectively, which are associated with the at least a first non-volatile storage element during at least a portion of a time in which the first voltage is applied, the source and p-well voltages exceed the first voltage, and (c) determine whether the at least a first non-volatile storage element is in a conductive state or a non-conductive state using current sensing while applying the first voltage and the source and p-well voltages.
