    Abstract: A variable resistance memory device includes a pattern of one or more first conductive lines, a pattern of one or more second conductive lines, and a memory structure between the first and second conductive lines. The pattern of first conductive lines extends in a first direction on a substrate, and the first conductive lines extend in a second direction crossing the first direction. The pattern of second conductive lines extends in the second direction on the first conductive lines, and the second conductive lines extend in the first direction. The memory structure vertically overlaps a first conductive line and a second conductive line. The memory structure includes an electrode structure, an insulation pattern on a central upper surface of the electrode structure, and a variable resistance pattern on an edge upper surface of the electrode structure. The variable resistance pattern at least partially covers a sidewall of the insulation pattern.

    Abstract: A variable resistance memory device includes first conductive lines positioned above a substrate. Each of the first conductive lines extends in a first direction and a second direction. Second conductive lines extend in the first direction and the second direction. The second conductive lines are positioned above the first conductive lines. A memory is positioned between the first and second conductive lines. The memory unit overlaps the first and second conductive lines in a third direction. The memory unit includes a first electrode, a variable resistance pattern positioned on the first electrode, and a second electrode positioned on the variable resistance pattern. A selection pattern is positioned on each memory unit. A third electrode is positioned above the selection pattern. The third electrode is in direct contact with a lower surface of each of the second conductive lines.

    Abstract: Forming a semiconductor device that includes a memory cell array may include performing a switching firing operation on one or more memory cells of the memory array to cause a threshold voltage distribution associated with threshold switching devices in the memory cells to be reduced. The switching device firing operation may be performed such that the threshold voltage distribution is reduced while maintaining the one or more threshold switching devices in the amorphous state. Performing the switching device firing operation on a threshold switching device may include heating the threshold switching device, applying a voltage to the threshold switching device, applying a current to the threshold switching device, some combination thereof, or the like.
