Patent ID: 8883604

Claim:
A method of forming a nonvolatile memory cell, comprising: forming support material having an elevationally outer surface, a first sidewall joined and angling relative to the elevationally outer surface, and an elevationally inner surface joined and angling relative to the first sidewall; forming a first current conductive electrode material elevationally over the elevationally outer surface, laterally of and laterally over the first sidewall, and directly against the elevationally inner surface; removing the first current conductive material from being elevationally over the elevationally outer surface and from being directly against most of the elevationally inner surface to form a first platelike electrode having one sidewall against the first sidewall and another sidewall opposite the one sidewall that is laterally outwardly exposed; forming a second sidewall elevationally outward of the first platelike electrode, the first and second sidewalls being formed at an angle relative one another; forming an ion conductive material over the second sidewall and directly against an elevationally outer surface of the first platelike electrode, the ion conductive material and the first current conductive electrode material of the first platelike electrode contacting one another at a maximum contacting area defined by a transverse thickness of the ion conductive material and a transverse thickness of the first current conductive electrode material where such cross at said angle; and providing a second current conductive electrode material directly against the ion conductive material, at least one of the first current conductive electrode material and the second current conductive electrode material having an electrochemically active surface directly against the ion conductive material.
