A phase change pattern is disposed on the interlayer insulating layer to cover the top surface and the side surface of the protruding portion of the heater plug. An insulating spacer is interposed between the phase change pattern and the side surface of the protruding portion of the heater plug. A capping electrode is disposed on the phase change pattern.
