Abstract

A memory cell may include a phase-change material. Adhesion between the phase-change material and a dielectric or other substrate may be enhanced by using an adhesion enhancing interfacial layer. Conduction past the phase-change material through the interfacial layer may be reduced by providing a discontinuity or other feature that reduces or prevents conduction along said interfacial layer.
