1. A phase-change memory device comprising:
a heat-generating electrode layer;
a first insulating layer partially covering the heat-generating electrode layer, exposing a portion of the heat-generating electrode layer, and having a pore therein; and
an antimony (Sb)-selenium (Se) chalcogenide SbxSe100-x phase-change material layer contacting the portion of the heat-generating electrode layer exposed through the pore, and filling the pore.
