    摘要: According to some embodiments of the present invention, there are provided PRAMS having a phase-change layer pattern interposed between a molding layer and a forming layer pattern, and methods of forming the same that include a node conductive layer pattern, a molding layer, a forming layer pattern and a protecting layer. The molding layer, the forming layer pattern and the protecting layer are formed to cover the planarized interlayer insulating layer and the node conductive layer pattern. A lower electrode is interposed between the molding layer and the planarized interlayer insulating layer. A phase-change layer pattern is formed on the planarized interlayer insulating layer. A spacer pattern is disposed between the phase-change layer pattern and the molding layer.

    摘要: A phase-change memory device includes a phase-change memory cell having a volume of material which is programmable between amorphous and crystalline states. A write current source selectively applies a first write current pulse to program the phase-change memory cell into the amorphous state and a second write current pulse to program the phase-change memory cell into the crystalline state. The phase-change memory device further includes a restore circuit which selectively applies the first current pulse to the phase-change memory cell to restore at least an amorphous state of the phase-change memory cell.
