Claim 0:
1. An apparatus, comprising:
a substrate defining a plane in a first direction and a second direction, and extending in a third direction orthogonal to the plane;
a first electrode;
a second electrode; and
a self-selecting storage element extending between the first electrode and the second electrode in the first direction parallel with the plane of the substrate, wherein the self-selecting storage element comprises a bulk region comprising a chalcogenide material having a first composition and a sidewall region comprising the chalcogenide material having a second composition that is different than the first composition, at least a portion of the sidewall region extending between the first electrode and the second electrode in the first direction, wherein a first concentration of one or more components in the first composition of the chalcogenide material is between two and twenty percent different than a second concentration of the one or more components in the second composition.
