Abstract
A phase-change memory device includes a first insulator having a hole therethrough, a first electrode that conforms at least partially to the hole, a phase-change material in electrical communication with the first electrode, and a second electrode in electrical communication with the phase-change material. When current is passed from the first electrode to the second electrode through the phase-change material, at least one of the first and second electrodes remains unreactive with the phase change material.
