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.

Claim (Index 9):
A method of performing a read operation of a three-dimensional (3D) flash memory device, the 3D flash memory device comprising a plurality of cell strings, each of the plurality of cell strings including a string select transistor, a plurality of memory cells and a ground select transistor stacked in a direction perpendicular to a substrate, the method comprising:\n applying a first turn-on voltage to a selected string selection line among a plurality of string selection lines connected to a plurality of string selection transistors of the plurality of cell strings; applying a second turn-on voltage and a third turn on voltage to a first unselected string selection line and a second unselected string selection line respectively among the plurality of string selection lines; applying a fourth turn-on voltage to a selected ground selection line among a plurality of ground selection lines connected to a plurality of ground selection transistors of the plurality of cell strings; after applying the first through fourth turn-on voltages the decoder is further configured to adjust a first voltage of the first unselected string selection line to a first level; and after adjusting the voltage of the first unselected string selection line the decoder is further configured to adjust a second voltage of the second unselected string selection line to a second level, wherein string selection transistors, among the plurality of string selection transistors, connected to the selected string selection line and ground selection transistors, among the plurality of ground selection transistors, connected to the selected ground selection line are turned-on while the first voltage and the second voltage are adjusted.
