    Abstract: A non-volatile memory device includes a substrate, a memory cell string including a vertical channel structure and memory cells, a voltage generator including a first transistor and configured to provide various voltages to the memory cells, and a vertical capacitor structure. The vertical capacitor structure includes first and second active patterns apart from each other in a first horizontal direction, a first gate pattern located above a channel region between the first and second active patterns, a first gate insulating film between the first gate pattern and the substrate in a vertical direction, and capacitor electrodes each extending in the vertical direction. The first transistor includes a second gate pattern and a second gate insulating film between the second gate pattern and the substrate in the vertical direction. The first gate insulating film has a thickness greater than a thickness of the second gate insulating film in the vertical direction.

    Abstract: A memory device is provided. The memory device includes: a first cell region provided in a first layer and including a first bit line and a first redundant bit line; a second cell region provided in a second layer and including a second bit line and a second redundant bit line; a peripheral region provided in a third layer and including first page buffers configured to be respectively connected to the first bit line and the second bit line, and a second page buffer configured to be commonly connected to the first redundant bit line and the second redundant bit line; and a control circuit configured to: based on the first bit line being defective, replace the first bit line with the first redundant bit line; and based on the second bit line being defective, replace the second bit line with the second redundant bit line.
