Abstract
A vertical memory device includes gate electrodes on a substrate and a first structure. The gate electrodes may be spaced apart from each other in a first direction perpendicular to an upper surface of the substrate. The first structure extends through the gate electrodes in the first direction, and includes a channel and a variable resistance structure sequentially stacked in a horizontal direction parallel to the upper surface of the substrate. The variable resistance structure may include quantum dots (QDs) therein.
