Abstract: A memory cell can include a chalcogenide material having a narrowed end. A conductive material can be positioned at the narrowed end of the chalcogenide material. A dielectric barrier layer can be disposed between the conductive material and the narrowed end of the chalcogenide material. A dielectric spacer material can be positioned along a narrowed segment of the chalcogenide material.
