    Abstract: A vertical memory device includes conductive lines on a substrate, first and second semiconductor patterns, first and second pads, first and second electrodes, a third electrode, and a first division pattern. The conductive lines are stacked in a vertical direction and extend in a first direction. The first and second semiconductor patterns extend through the conductive lines in the vertical direction. The first and second pads are formed on the first and second semiconductor patterns. The first and second electrodes are electrically connected to the first and second pads. The third electrode is electrically connected to a first conductive line of the conductive lines. The first division pattern extends in a second direction, and extends through and divides the first conductive line. In a plan view, the first and second semiconductor patterns and the first conductive line are disposed at one side of the first division pattern.
