Methods for producing RRAM resistive switching elements having reduced forming voltage include preventing formation of interfacial layers, and creating electronic defects in a dielectric film. Suppressing interfacial layers in an electrode reduces forming voltage. Electronic defects in a dielectric film foster formation of conductive pathways.
