A method for manufacturing a mushroom-cell type phase change memory is based upon manufacturing a pillar of bottom electrode material upon a substrate including an array of conductive contacts in electrical communication with access circuitry. A layer of electrode material is deposited making reliable electrical contact with the array of conductive contacts. Electrode material is etched to form a pattern of electrode pillars on corresponding conductive contacts. Next, a dielectric material is deposited over the pattern and planarized to provide an electrode surface exposing top surfaces of the electrode pillars. Next, a layer of programmable resistive material, such as a chalcogenide or other phase change material, is deposited, followed by deposition of a layer of a top electrode material.
