Abstract: A three-dimensional (3D) semiconductor memory device includes a substrate including a cell array region, a connection region, and a block selection region between the cell array and connection regions, a stack structure including horizontal layers vertically stacked on the substrate, each of the horizontal layers including electrode portions extending in a first direction on the cell array and block selection regions and a connecting portion disposed on the connection region to connect the electrode portions in a second direction perpendicular to the first direction, and block selection gate electrodes intersecting sidewalls of the electrode portions of the horizontal layers on the block selection region. Each of the electrode portions includes a first semiconductor region having a first conductivity type on the cell array region and includes a channel dopant region having a second conductivity type different from the first conductivity type on the block selection region.

Abstract: A method of operating a memory controller, the memory controller configured to control a nonvolatile memory device, the nonvolatile memory device including a plurality of memory blocks. The method including detecting an invalid block among the plurality of memory blocks; determining an invalid pattern based on a state of the invalid block; and performing an operation on the invalid block such that the invalid block has the invalid pattern.
