Abstract
For decreasing a recording current and suppressing a cross erase simultaneously, a three-dimensional phase-change memory for attaining higher sensitivity and higher reliability by the provision of a chalcogenide type interface layer is provided, in which an electric resistivity, a thermal conductivity, and a melting point of the material of the interface layer are selected appropriately, thereby improving the current concentration to the phase-change material and thermal and material insulation property with Si channel upon writing.
