    Abstract: Three-dimensional semiconductor memory devices are provided. A three-dimensional semiconductor memory device includes a stack structure that includes gate electrodes on a substrate. The three-dimensional semiconductor memory device includes a first vertical structure, a second vertical structure, a third vertical structure, and a fourth vertical structure that penetrate the stack structure and are sequentially arranged in a zigzag shape along a first direction. Moreover, the three-dimensional semiconductor memory device includes a first bit line that extends in the first direction. The first bit line vertically overlaps the second vertical structure and the fourth vertical structure. Centers of the second and fourth vertical structures are spaced apart at the same distance from the first bit line. The first vertical structure is spaced apart at a first distance from the first bit line. The third vertical structure is spaced apart at a second distance from the first bit line.

    Abstract: A semiconductor device includes a gate electrode on a substrate, a channel surrounding sidewalls of the gate electrode on the substrate, and source/drain electrodes on the substrate at opposite sides of the gate electrode in a first direction parallel to an upper surface of the substrate. A thickness of the channel from the gate electrode to the source/drain electrodes in a horizontal direction parallel to the upper surface of the substrate is not constant but varies in a vertical direction perpendicular to the upper surface of the substrate.

    Abstract: Three-dimensional semiconductor memory devices are provided. A three-dimensional semiconductor memory device includes a plurality of word line blocks including a plurality of cell strings that are connected in parallel between a bit line and a common source line. Each of the cell strings includes a plurality of memory cell transistors that are stacked on a substrate in a vertical direction, a plurality of ground selection transistors that are connected in series between the plurality of memory cell transistors and the substrate, and a string selection transistor that is between the plurality of memory cell transistors and the bit line. In each of the cell strings, at least one of the plurality of ground selection transistors has a first threshold voltage, and remaining ones of the ground selection transistors have a second threshold voltage different from the first threshold voltage. Related methods of operating three-dimensional semiconductor memory devices are also provided.
