    摘要: A storage node may include a bottom electrode contact layer, a phase change layer connected to the bottom electrode contact layer, and a top electrode layer connected to the phase change layer. The bottom electrode contact layer may protrude toward the phase change layer. A phase change memory device may include a switching device and the storage node. The switching device may be connected to the bottom electrode contact layer. A method of manufacturing the storage node may include forming a via hole in an insulating interlayer, at least partially filling the via hole to form a bottom electrode contact layer, protruding the bottom electrode contact layer from the via hole, and forming a phase change layer that covers the bottom electrode contact layer. A method of manufacturing a phase change memory device may include forming the switching device on a substrate and manufacturing the storage node.

    摘要: Provided are phase change random access memory (PRAM) devices and methods of operating the same. The PRAM device may include a switching device, a lower electrode, a lower electrode contact layer, a phase change layer and/or an upper electrode. The lower electrode may be connected to a switching device. The lower electrode contact layer may be formed on the lower electrode. The phase change layer, which may include a bottom surface that contacts an upper surface of the lower electrode contact layer, may be formed on the lower electrode contact layer. The upper electrode may be formed on the phase change layer. The lower electrode contact layer may be formed of a material layer having an absolute value of a Seebeck coefficient higher than TiAlN. The Seebeck coefficient of the lower electrode contact layer may be negative. The material layer may have lower heat conductivity and/or approximately equivalent electrical resistance as TiAlN.

    摘要: Provided is a method of operating a phase change random access memory comprising a switching device and a storage node comprising a phase change layer. The method includes applying a reset current passing through the phase change layer from a lower portion of the phase change layer toward an upper portion of the phase change layer and being smaller than 1.6 mA to the storage node to change a portion of the phase change layer into an amorphous state. The set voltage is in an opposite direction is exemplary embodiments, and a connector is of small cross-sectional area.
