    Abstract: Disclosed is a memory device which includes a memory cell array that includes a plurality of memory cells, and a peripheral circuit configured to perform a plurality of operations on the memory cell array by using a plurality of operating voltages. The peripheral circuit includes a voltage generating circuit including a first pump block, a second pump block, and a common pump block. The voltage generating circuit connects the first pump block and the common pump block in parallel to generate a first operating voltage among the plurality of operating voltages and connects the common pump block and the second pump block in series to generate a second operating voltage among the plurality of operating voltages. The common pump block is configurable to match the first pump block, the second pump block, or both, as needed.

    Abstract: A nonvolatile memory device includes a memory cell region, a peripheral circuit region, a memory block in the memory cell region, and a control circuit in the peripheral circuit region. The memory cell region includes a first metal pad. The peripheral circuit region includes a second metal pad and is vertically connected to the memory cell region by the first metal pad and the second metal pad. The memory block includes a plurality of memory cells disposed in a vertical direction. The control circuit applies an erase voltage to an erase source terminal of the memory block, and applies a first voltage to a first selection line among a plurality of selection lines in the memory block. The first voltage is higher than the erase voltage. The first selection line is disposed closest to the erase source terminal among the plurality of selection lines and is used for selecting the memory block as an erase target block.
