Abstract:
1. A method of forming a non-volatile resistive oxide memory cell, comprising: forming a first conductive electrode of the memory cell as part of a substrate; depositing insulative material over the first electrode; forming an opening into the insulative material over the first electrode, the opening comprising sidewalls and a base, the opening comprising an elongated trench in the insulative material having a via extending therefrom to the first conductive electrode; lining the opening sidewalls and base with a multi-resistive state layer comprising multi-resistive state metal oxide-comprising material which less than fills the opening; and forming a second conductive electrode of the memory cell within the opening laterally inward of the multi-resistive state layer lining the sidewalls and elevationally over the multi-resistive state layer lining the base.
