Abstract
A memory device comprises an array of memory cells each capable of storing multiple bits of data. The memory cells are arranged in memory strings that are connected to a common source line. Each memory cell includes a programmable transistor connected in parallel with a resistance switching device. The transistor is switchable between a plurality of different threshold voltages associated with respective memory states. The resistance switching device is configured to be switchable between a plurality of different resistances associated with respective memory states.
