An apparatus for high density memory with integrated logic. Specifically, a three terminal resistive random access memory (ReRAM) device having Schottky barriers that can switch from a low resistive state to a high resistive state is provided. The Schottky transistor memory device includes an insulating layer, a source region disposed on the insulating layer, a drain region disposed on the insulating layer, a binary or complex oxide memory material, a gate dielectric layer, and a gate electrode. As voltage is applied the Schottky barrier breaks down leading to the formation of a conductive anodic filament (CAF). The CAF is non-volatile and short-circuits the reverse-biased barrier thus keeping the device in a low resistance state. Removing the CAF switches the device back to a high resistance state. Thus, a new type of semiconductor device advantageously combines computation and memory further providing for very high density NAND chains.
