Abstract
A semiconductor memory device includes a cell array region and a peripheral circuit region. The cell array region includes an electrode structure including a plurality of electrodes sequentially stacked on a body conductive layer, and vertical structures penetrating the electrode structure so as to be connected to the body conductive layer. The peripheral circuit region includes a remaining substrate on the body conductive layer. The remaining substrate includes a buried insulating layer, and a peripheral active layer that is provided on the buried insulating layer and is substantially single-crystalline.
