Abstract:
A method of forming a non-volatile resistive oxide memory cell includes forming a first conductive electrode of the memory cell as part of a substrate. The first conductive electrode has an elevationally outermost surface and opposing laterally outermost edges at the elevationally outermost surface in one planar cross section. Multi-resistive state metal oxide-comprising material is formed over the first conductive electrode. Conductive material is deposited over the multi-resistive state metal oxide-comprising material. A second conductive electrode of the memory cell which comprises the conductive material is received over the multi-resistive state metal oxide-comprising material. The forming thereof includes etching through the conductive material to form opposing laterally outermost conductive edges of said conductive material in the one planar cross section at the conclusion of said etching which are received laterally outward of the opposing laterally outermost edges of the first conductive electrode in the one planar cross section.
