Abstract
A memory device includes a cell region in which memory blocks, respectively including gate electrodes and insulating layers, alternately stacked on a substrate, and channel structures, extending in a first direction, perpendicular to an upper surface of the substrate, passing through the gate electrodes and the insulating layers, and connected to the substrate, are arranged. A peripheral circuit region includes a row decoder connected to the gate electrodes and a page buffer connected to the channel structures. The memory blocks include main blocks and at least one spare block, wherein a length of the spare block is shorter than a length of each of the main blocks, in a second direction, parallel to the upper surface of the substrate.
