Abstract:
A resistive random access memory device, a method for manufacturing the resistive random access memory device, and a method for operating the resistive random access memory device are disclosed. The resistive random access memory device includes a resistive switching memory element including two electrodes and a layer of variable-resistance material between the two electrodes, wherein the layer of variable-resistance material exhibits bipolar resistive switching behavior; and a Schottky diode including a metal layer and a p-doped semiconductor layer which contact each other, wherein the metal layer of the Schottky diode is coupled to one of the two electrodes of the resistive switching memory element. The present disclosure provides the resistive random access memory device operating in bipolar resistive switching scheme.
