Abstract:
A three-dimensional (3D) flash memory includes a first dummy word line disposed between a ground select line and a lowermost main word line, and a second dummy word line of different word line configuration disposed between a string select line and an upper most main word line.

Claim (Index 16):
A data storage device comprising:\n a three-dimensional (3D) flash memory device comprising a plurality of memory blocks, each of the plurality of memory blocks including a plurality of cell strings arranged, each of the plurality of cell strings including a string select transistor, first and second dummy transistors, a plurality of memory cells, third and fourth dummy transistors and a ground select transistor stacked in a direction perpendicular to a substrate; and a controller configured to transmit an erase command and an address indicating a selected memory block among the plurality of memory blocks to the 3D flash memory device, wherein the 3D flash memory device further comprises: a dummy word line voltage generator configured to provide a first voltage to the first dummy word line connected to the first dummy transistor, a second voltage to a second dummy word line connected to the second dummy transistor, a third voltage to a third dummy word line connected to the third dummy transistor, and a fourth voltage to a fourth dummy word line connected to the fourth dummy transistors during an erase operation; and a word line voltage generator configured to apply a fifth voltage to a plurality of main word lines connected to the plurality of memory cells respectively during the erase operation, wherein the second dummy transistor and the third dummy transistor are disposed between the first dummy transistor and the fourth dummy transistor, the second voltage and the third voltage are the same, and the second voltage is different from the first voltage and the fourth voltage.
