    摘要: Semiconductor memory devices and methods of fabricating the same are provided. A semiconductor memory device includes stack gate structures that are spaced apart from each other in a first direction horizontal to a substrate. Each of the stack gate structures includes insulating layers and gate electrodes alternately and repeatedly stacked on the substrate. Vertical channel structures penetrate the stack gate structures. A source plug line is provided between the stack gate structures. The source plug line is in contact with the substrate and extends in a second direction intersecting the first direction. The substrate being in contact with the source plug line includes a plurality of protruding regions formed along the second direction. Each of the protruding regions has a first width, and the protruding regions are spaced apart from each other by a first distance greater than the first width.
