A memory device and a method of fabricating the same are provided. The method includes forming a gate stack structure on a semiconductor substrate and partially exposing upper end portions of the semiconductor substrate by etching ends of the gate stack structure, and implanting a dopant into the exposed portions of the semiconductor substrate to form source and drain regions, wherein the gate stack structure is etched such that its width increases from top to bottom. Accordingly, it is possible to manufacture a memory device with high integration, using a simplified manufacture process.

A nonvolatile memory device comprises a substrate, a switching device and a data storage unit connected to the switching device. The data storage unit includes a data storage material layer in the form of a transition metal oxide layer having different resistance characteristics in different voltage ranges. The data storage material layer has a first resistance when a write voltage V W1 , 0 4 ≤V W1 , is applied to the data storage material layer, the first resistance representing a first data state. The data storage material layer also has a second resistance different from the first resistance when a write voltage V E1 , V E1 ≤V 5 R , V 5 R 4 , to the data storage material layer without altering the data state of the data storage material layer.

A nonvolatile memory device comprises a substrate, a diode with a switching function formed on the substrate, and a data storage unit connected to the diode. The data storage unit includes a data storage material layer having different resistance characteristics in different voltage ranges. The data storage material layer has a first resistance when a write voltage V w1 (0 1 w1 2 ) is applied to the data storage material layer, the first resistance representing a first data state. The data storage material layer has a second resistance different from the first resistance when a write voltage V 3 (V 2 3 ) is applied to the data storage material layer, the second resistance representing a second data state. The first and second data states are readable from the data storage material layer by application of a read voltage V R (V R 1 |) to the data storage material layer without altering the data state of the data storage material layer.
