Abstract

A phase-change memory cell may be formed with a carbon-containing interfacial layer that heats a phase-change material. By forming the phase-change material in contact, in one embodiment, with the carbon containing interfacial layer, the amount of heat that may be applied to the phase-change material, at a given current and temperature, may be increased. In some embodiments, the performance of the interfacial layer at high temperatures may be improved by using a wide band gap semiconductor material such as silicon carbide.
