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.
