    摘要: According to example embodiments, a memory device includes a memory cell array, a controller including a normal program controller and a dummy program controller, and a driver. The memory cell array includes a first memory block on a substrate. The first memory block includes a plurality of cell strings on the substrate extending in a vertical direction. The normal program controller is configured to generate a first control signal for programming normal cells of a selected cell string that is selected based on an address received by the controller. The dummy program controller is configured to generate a second control signal for programming at least one dummy cell included in each of the plurality of cell strings before generation of the first control signal. The driver is configured to apply a first operation voltage set for programming the normal cells of the selected cell string to the first memory block in response to the first controller signal. The driver is configured to apply a second operation voltage set for programming the at least one dummy cell to the first memory block in response to the second control signal.

    摘要: A nonvolatile memory device includes a 3D memory cell array having words lines that extend from a lowest memory cell array layer closest to a substrate to a highest memory cell array layer farthest from the substrate, a voltage generator circuit generating first and second voltage signals, and a row selecting circuit that simultaneously applies the first voltage signal to a selected word line and the second voltage signal to an unselected word line. The selected word line and the unselected word line have different resistances, yet the first voltage signal is applied to the selected word line and the second voltage signal is applied to the unselected word line with a same rising slope over a defined period of time.
