Abstract: Three-dimensional semiconductor memory devices and methods of fabricating the same. The three-dimensional semiconductor devices include an electrode structure with sequentially-stacked electrodes disposed on a substrate, semiconductor patterns penetrating the electrode structure, and memory elements including a first pattern and a second pattern interposed between the semiconductor patterns and the electrode structure, the first pattern vertically extending to cross the electrodes and the second pattern horizontally extending to cross the semiconductor patterns.

Abstract: A three-dimensional (3D) semiconductor memory device includes an electrode separation pattern, a stack structure, a data storage layer, and a channel structure. The electrode separation pattern is disposed on a substrate. A stack structure is disposed on a sidewall of the electrode separation pattern. The stack structure includes a corrugated sidewall opposite to the sidewall of the electrode separation pattern. The sidewall of the electrode separation pattern is vertical to the substrate. A data storage layer is disposed on the corrugated sidewall. A channel structure is disposed on the charge storage layer.
