Classification: CPC G | IPC G

Claim 8:
9. A method of programming in a nonvolatile memory device, the nonvolatile memory device comprising a cell region including a plurality of first metal pads and a peripheral region including a plurality of second metal pads and vertically connected to the cell region by the plurality of first metal pads and the plurality of second metal pads, the method comprising:
providing a memory block in the cell region, the memory block comprising a plurality of sub blocks disposed in a vertical direction where the memory block includes a plurality of cell strings connected to a plurality of bit lines, each cell string comprising a plurality of memory cells connected in series and disposed in the vertical direction;
providing a plurality of intermediate switching transistors disposed in a boundary portion between two adjacent sub blocks in the vertical direction; and
selectively activating, by a control circuit in the peripheral region, each of the plurality of intermediate switching transistors based on a program address during a program operation,
wherein selectively activating each of the plurality of intermediate switching transistors includes turning on one or more intermediate switching transistors in a selected cell string and turning off one or more intermediate switching transistors in an unselected cell string adjacent to the selected cell string in a first direction, based on the program address, and
wherein the selected cell string and the unselected cell string are connected to a first bit line of the plurality of bit lines.
