Abstract:
A method of operating a three-dimensional memory device includes applying a target string bias voltage to a selected drain select gate electrode which partially surrounds a row of memory stack structures that directly contact a drain select isolation structure, and applying a neighboring string bias voltage that has a greater magnitude than the target string bias voltage to an unselected drain select gate electrode that contacts the drain select level isolation structure.

Claim (Index 22):
The three-dimensional memory device of  claim 20 , further comprising a pair of dielectric material portions that laterally extend along an additional horizontal direction and located on either side of the stack, wherein:\n the electrically conductive layers comprise word line electrically conductive layers that laterally extend between the pair of dielectric material portions; \n the drain select level isolation structures are located between the pair of dielectric material portions and laterally extend along the additional horizontal direction and laterally separate drain select gate electrode layer sections; \n each of the drain select level isolation structures generally extends along the additional horizontal direction and includes a pair of lengthwise sidewalls; \n each of the pair of lengthwise sidewalls includes an alternating sequence of planar sidewalls and concave vertical sidewalls; and \n each of the concave vertical sidewalls contacts a respective one of the memory stack structures.
