Abstract:
1. A nonvolatile memory element comprising: a first electrode layer; a second electrode layer; a resistive switching layer disposed between the first electrode layer and the second electrode layer; a first encapsulation layer formed between and directly contacting a first device interconnect layer and a bottom surface of the first electrode layer; and a second encapsulation layer formed between and directly contacting a top surface of the second electrode layer and a second device interconnect layer, wherein the first electrode layer, the second electrode layer and the resistive switching layer each comprise the same metal, and wherein the first encapsulation layer and the second encapsulation layer each include a material that is reactive with oxygen, wherein the first and second encapsulation layers comprise one or more of copper, aluminum, indium, gallium, niobium, or magnesium.
