Abstract:
A phase change memory cell includes a first electrode having a cylindrical portion. A dielectric material having a cylindrical portion is longitudinally over the cylindrical portion of the first electrode. Heater material is radially inward of and electrically coupled to the cylindrical portion of the first electrode. Phase change material is over the heater material and a second electrode is electrically coupled to the phase change material. Other embodiments are disclosed, including methods of forming memory cells which include first and second electrodes having phase change material and heater material in electrical series there-between.
