    摘要： Methods are provided for operating a magnetic random access memory device including a memory cell having a magnetic tunnel junction structure on a substrate. In particular, a writing current pulse may be provided through the magnetic tunnel junction structure, and a writing magnetic field pulse may be provided through the magnetic tunnel junction structure. In addition, at least a portion of the writing magnetic field pulse may be overlapping in time with respect to at least a portion of the writing current pulse, and at least a portion of the writing current pulse and/or at least a portion of the writing magnetic field pulse may be non-overlapping in time with respect to the other. Related devices are also discussed.

    摘要： In an embodiment, a phase change memory device includes a semiconductor substrate of a first conductivity type and a first interlayer insulating layer disposed on the semiconductor substrate. A hole penetrates the first interlayer insulating layer. A first and a second semiconductor pattern are sequentially stacked in a lower region of the hole. A cell electrode is provided on the second semiconductor pattern. The cell electrode has a lower surface than a top surface of the first interlayer insulating layer. A confined phase change material pattern fills the hole on the cell electrode. An upper electrode is disposed on the phase change material pattern. The phase change material pattern in the hole is self-aligned with the first and second semiconductor patterns by the hole. A method of fabricating the phase change memory device is also provided.
