  • Publication number: 20220020434
    Abstract: Each of memory blocks of a nonvolatile memory device includes a memory cell region including first metal pads, first memory cells of a first portion of pillar, and second memory cells of a second portion of the pillar, and a peripheral circuit region including second metal pads, a row decoder, and a page buffer. When performing program operations based on consecutive addresses at a memory block selected from the memory blocks, the nonvolatile memory device sequentially completes first program operations of non-adjacent memory cells not adjacent to a boundary of the first portion and the second portion from among the first and second memory cells and then completes a second program operation of an adjacent memory cell adjacent to the boundary. The peripheral circuit region is vertically connected to the memory cell region by the first metal pads and the second metal pads directly.
