ABSTRACT:
Provided are a phase-change nonvolatile memory device and a manufacturing method thereof. The device includes: a substrate; and a stack structure disposed on the substrate and including a phase-change material layer. The phase-change material layer is formed of an alloy of antimony (Sb) and zinc (Zn), so that the phase-change memory device can stably operate at high speed and reduce power consumption.
