Abstract
The present disclosure relates to resistive random-access memory (RRAM) devices. A method for fabricating resistive random-access memory (RRAM) device may include fabricating, on a first electrode of the RRAM device, a first interface layer comprising a first discontinuous film of a first material; fabricating, on the first interface layer, a switching oxide layer comprising at least one transition metal oxide; fabricating a second interface layer on the switching oxide layer; and fabricating a defect engineering layer on the second interface layer. The first material is more chemically stable than the at least one transition metal oxide. The defect engineering layer includes a layer of Ti in some embodiments.
