Abstract: A phase change material layer and a phase change memory device comprising the same are provided to achieve low melting point and high re-crystallization temperature and obtain a reduced reset current and a favorable retention property. A phase change material layer(10) adds at least one of In or Ga into Sb. The phase change material layer is formed in a range of intermetallic composition to eutectic composition. The phase change material layer may contain at least one of Sb and In, or Ga. A phase change memory device includes a storage node having a phase change material layer and switching devices connected to the storage node.

Abstract: Carbon containing phase change material, a memory device including the same and an operation method thereof are provided to use a carbon containing IST layer as a phase-change layer which is maintained in a single phase, thereby ensuring thermal stability and lowering reset currents as preventing intercell interference caused by heat. Phase change material comprises a major compound and additive. The major compound is In-Sb-Te. The additive uses carbon which is added as much as it can maintain the phase change material in a single phase. The content(a) of the carbon can be 0.005
