    Abstract: A three-dimensional (3D) semiconductor memory device is provided. The device includes: a memory cell region; and a peripheral circuit configured to control the memory cell region. The memory cell region includes: a cell array region including memory cells arranged vertically along a vertical direction; and a connection region including ends of word lines that are connected to the memory cells, wherein the ends form a stair-step configuration. The peripheral circuit includes a peripheral circuit region overlapping the connection region along the vertical direction. The peripheral circuit region includes a first main pass transistor electrically connected to a first word line of the word lines, and a first dummy pass transistor electrically separated from the word lines. The first main pass transistor and the first dummy pass transistor are arranged along a first direction perpendicular to the vertical direction.
