Abstract:
A three-dimensional (3D) nonvolatile memory device includes a cell string. The cell string includes a pillar structure comprising a ground selection transistor, a plurality of memory cells, and a string selection transistor stacked vertically over a substrate. The memory cells comprise a first cell group and a second cell group stacked on the first cell group, and a horizontal width of at least a portion of the pillar structure decreases in a depth direction towards the substrate. A method of programming the memory device includes initializing a channel of a memory cell of the first cell group of the cell string through the ground selection transistor of the pillar structure, and then applying a program voltage to the memory cell of the pillar structure of the cell string.

Claim (Index 33):
A method of programming a three-dimensional (3D) nonvolatile memory device, including a memory cell array having a plurality of cell strings each connected to one of a plurality of bit lines, the cell strings each including a pillar structure comprising a ground selection transistor, a plurality of memory cells each connected to one of a plurality of word lines, and a string selection transistor stacked vertically over a substrate, wherein the memory cells of each cell string comprise a first cell group and a second cell group stacked on the first cell group, and wherein a horizontal width of at least a portion of the pillar structure decreases in a depth direction towards the substrate, the method comprising:\n providing bit line voltages to the bit lines to select one of the bit lines; supplying string selection line voltages to string selection transistors of cell strings connected to the selected bit line to select one of the cell strings; and precharging the pillar structure of the selected cell string through the ground selection transistor of the pillar structure, and then applying word line voltages to the word lines connected to the memory cells of the cell string to program a selected memory cell.
