Claim:
1. A method of forming a non-volatile resistive oxide memory cell, comprising: forming a conductive electrode of the memory cell as part of a substrate; forming metal oxid-comprising material over the first conductive electrode; depositing etch stop material over the metal oxide-comprising material, the etch stop material comprising silicon dioxide; depositing damascene template material over the etch stop material; etching an opening through the damascene template material to the etch stop material over the first electrode to stop relative to the etch stop material; after etching the opening through the damascene template material to the etching the material over the first electrode to stop relative to the etch stop material, etching through the etch stop material within the opening to the metal oxide-comprising material, the etching through the etch stop material comprising using at least one of a) NH after etching through the etch stop material within the opening to the metal oxide-comprising material, depositing conductive material to within the opening over the metal oxide-comprising material and the first conductive electrode and forming a second conductive electrode of the memory cell from the conductive material.
