    摘要: A nonvolatile memory device and a method of fabricating the same are provided. The nonvolatile memory device includes a conductive pillar that extends from a substrate in a first direction, a variable resistor that surrounds the conductive pillar, a switching material layer that surrounds the variable resistor, a first conductive layer that extends in a second direction, and a first electrode that extends in a third direction and contacts the first conductive layer and the switching material layer. Not one of the first, second, and third directions is parallel to another one of the first, second, and third directions.

    摘要: A non-volatile memory device includes a plurality of word lines, a plurality of bit lines, and an array of variable resistance memory cells each electrically connected between a respective word line and a respective bit line. Each of the memory cells includes first and second resistance variable patterns electrically connected in series between first and second electrodes. A material composition of the first resistance variable pattern is different than a material composition of the second resistance variable pattern. Multi-bit data states of each memory cell are defined by a contiguous increase in size of a programmable high-resistance volume within the first and second resistance variable patterns.

    摘要: Provided are methods of forming a phase change memory device. A semiconductor device having a lower electrode and an interlayer insulating layer may be prepared. The lower electrode may be surrounded by the interlayer insulating layer. Source gases, a reaction gas and a purge gas may be injected into a process chamber of a semiconductor fabrication device to form a phase change material layer on a semiconductor substrate. The source gases may be simultaneously injected into the process chamber. The phase change material layer may be in contact with the lower electrode through the interlayer insulating layer. The phase change material layer may be etched to form a phase change memory cell in the interlayer insulating layer. An upper electrode may be formed on the phase change memory cell.
