Abstract
A nonvolatile memory device includes a first semiconductor layer and a second semiconductor layer. The first semiconductor layer includes word-lines, bit-lines and a memory cell array which includes one or more memory blocks spaced apart from each other, one or more dummy blocks between the one or more memory blocks and a through-hole via region. The second semiconductor layer is under the first semiconductor layer includes a control circuit. The control circuit divides each of the one or more dummy blocks into an adjacent sub-block directly contacting the through-hole via region and a non-adjacent sub-block based on a relative distance from the through-hole via region in the first direction and uses each of the non-adjacent sub-blocks as a sub-block to store data.
