Non-volatile memory device and method of compensating leakage reading current of a non-volatile memory array

摘要

A non-volatile memory package includes a non-volatile memory array having a plurality of transistors that are electrically coupled in series, each of the transistors having an input terminal and an output terminal such that the output terminal of one of the transistors is coupled to the input terminal of a next transistor in a downstream direction. A read voltage supply supplies a voltage to the input terminal of a selected transistor of the plurality of transistors, to induce a cell current between the input terminal and the output terminal of the selected transistor. A bit sensor receives and evaluates a read current from the output terminal of the selected transistor. A shielding voltage applicator applies a voltage to the input terminal or the output terminal of a downstream transistor of the plurality of transistors, the downstream transistor being in the downstream direction from the selected transistor.
