    Abstract: Disclosed is a three-dimensional semiconductor memory device comprising a peripheral circuit structure on a first substrate, a second substrate on the peripheral circuit structure, first to fourth stack structures spaced apart in a first direction on the second substrate, first and second support connectors between the second and third stack structures, third and fourth support connectors between the third and fourth stack structures, and a through dielectric pattern penetrating the first stack structure and the second substrate. A first distance between the first and second support connectors is different from a second distance between the third and fourth support connectors.

    Abstract: A nonvolatile memory device may include a substrate; a first stacked structure on the substrate; a second stacked structure on the first stacked structure; a channel structure including a first portion passing through the first stacked structure and a second portion passing through the second stacked structure; and a filling structure including a first portion passing through the first stacked structure and extending in a first horizontal direction and a second portion passing through the second stacked structure and extending in the first horizontal direction. The upper end of the first portion of the filling structure may be at a same height as the upper end of the first portion of the channel structure.

    Abstract: A three-dimensional semiconductor memory device includes a substrate including a first connection region and a second connection region in a first direction and a cell array region between the first and second connection regions, and a first block structure on the substrate. The first block structure has a first width on the cell array region, the first block structure has a second width on the first connection region, and the first block structure has a third width on the second connection region. The first, second and third widths are parallel to a second direction intersecting the first direction, and the first width is less than the second width and is greater than the third width.
