Abstract: A nonvolatile memory device performs a read operation comprising first and second intervals. In the first interval the device applies a turn-on voltage to string selection lines and ground selection lines connected to the string selection transistors and the ground selection transistors, respectively. In the second interval, the device applies a turn-off voltage to unselected string selection lines and unselected ground selection lines while continuing to apply the turn-on voltage to a selected string selection line and a selected ground selection line. In both the first and second intervals, the device applies a first read voltage to a selected wordline connected to memory cells to be read by the read operation and applying a second read voltage to unselected wordlines among connected to memory cells not to be read by the read operation.

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.

Abstract: A nonvolatile memory may include; a first memory cell array including a first selection transistor connected to a first string selection line, a second memory cell array including a second selection transistor connected to a second string selection line and spaced apart from the first string selection line by a first cutting line, and a peripheral circuit. The peripheral circuit may provide a first program voltage to the first selection transistor, provide a second program voltage to the second selection transistor different from the first program voltage, program the first selection transistor with a first threshold voltage in response to the first program voltage, and program the second selection transistor with a second threshold voltage level greater than the first threshold voltage in response to the second program voltage.
