    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 fabricating a semiconductor device including a phase change layer. Methods may include forming a dielectric layer on a substrate, forming an opening in the dielectric layer and depositing, on the substrate having the opening, a phase change layer that contains an element that lowers a process temperature of a thermal treatment process to a temperature that is lower than a melting point of the phase change layer. Methods may include migrating a portion of the phase change layer from outside the opening, into the opening by the thermal treatment process that includes the process temperature that is lower than the melting point of the phase change layer.
