    摘要： There are provided PRAMS having a plurality of active regions located vertically in sequence and methods of forming the same. The PRAM and the method provide an approach to rapidly changing phase in a phase change layer pattern with a given design rule. A semiconductor substrate defining at least one reference active region is prepared in a cell array region and a peripheral circuit region. Other semiconductor substrates on a vertical line passing a main surface of the reference active region are located in sequence. The other semiconductor substrates define other active regions, respectively. A lower cell gate pattern is formed on the semiconductor substrate of the reference active region, and upper cell gate patterns are disposed on the other semiconductor substrates of the other active regions, respectively.

    摘要： A phase change memory device includes a mold layer disposed on a substrate, a heating electrode, a filling insulation pattern and a phase change material pattern. The heating electrode is disposed in an opening exposing the substrate through the mold layer. The heating electrode is formed in a substantially cylindrical shape, having its sidewalls conformally disposed on the lower inner walls of the opening. The filling insulation pattern fills an empty region surrounded by the sidewalls of the heating electrode. The phase change material pattern is disposed on the mold layer and downwardly extended to fill the empty part of the opening. The phase change material pattern contacts the top surfaces of the sidewalls of the heating electrode.
