    Abstract: A memory device includes memory blocks, each including memory cells, and peripheral circuits that control the memory blocks and execute an erase operation for each of the memory blocks. Each memory block includes word lines stacked on a substrate, channel structures extending perpendicular to an upper surface of the substrate and penetrating through the word lines, and a source region disposed on the substrate and connected to the channel structures. During an erase operation in which an erase voltage is input to the source region of a target memory block, the peripheral circuits reduce a voltage of a first word line from a first bias voltage to a second bias voltage at a first time and reduce a voltage of a second word line, different from the first word line, from a third bias voltage to a fourth bias voltage at a second time different from the first in time.

    Abstract: A nonvolatile memory device includes memory cell region including a first metal pad and a peripheral circuit region including a second metal pad, is connected to the memory cell region by the first metal pad and the second metal pad and includes including an address decoder and a page buffer circuit located on a first substrate. A memory cell array is provided in the memory cell region, which includes a first vertical structure on a second substrate. The first vertical structure includes first sub-blocks and first via areas in which one or more through-hole vias are provided, and through-hole vias pass through the first vertical structure. A control circuit in the peripheral circuit region groups the memory blocks into a plurality of groups based on whether the memory blocks is close to the first via areas and performs address re-mapping.

    Abstract: A non-volatile memory device is provided. The memory device includes: word lines stacked on a substrate; a string select lines on the word lines, the string select lines being spaced apart from each other in a first horizontal direction and extending in a second horizontal direction; and a memory cell array including memory blocks, each of which includes memory cells connected to the word lines and the string select lines. The string select lines include a first string select line, and a second string select line which is farther from a word line cut region than the first string select line, and a program operation performed on second memory cells connected to a selected word line and the second string select line is performed before a program operation performed on first memory cells connected to the selected word line and the first string select line.

    Abstract: A nonvolatile memory device includes a first semiconductor layer, a second semiconductor layer and a control circuit. The memory cell array includes a first vertical structure on the first upper substrate and a second vertical structure on the second upper substrate, the first vertical structure includes first sub-blocks and the second vertical structure includes second sub-blocks. The second semiconductor layer includes a lower substrate that includes address decoders and page buffer circuits. The first vertical structure includes first via areas in which one or more through-hole vias are provided, through-hole vias pass through the first vertical structure. The first sub-blocks are arranged among the first via areas and the second sub-blocks are arranged among the second via areas. The control circuit groups the memory blocks into a plurality of groups based on whether the memory blocks is close to the first via areas and performs address re-mapping.
