Abstract:
A memory device includes an alternating stack of insulating layers and electrically conductive layers. Vertical NAND strings are formed through the alternating stack, each of which includes a drain region, memory cell charge storage transistors, and a pair of drain select transistors in a series connection. A common bit line is electrically connected to drain regions of two vertical NAND strings. The drain select transistors of the two vertical NAND strings are configured such that drain select transistors sharing a first common drain select gate electrode provide a higher threshold voltage for one of the two vertical NAND strings, and drain select transistors sharing a second common drain select gate electrode provide a higher threshold voltage for the other of the two vertical NAND strings. The different threshold voltages can be provided by a combination of a masked ion implantation and selective charge injection.

Claim (Index 12):
The memory device of  claim 1 , wherein:\n each layer within the alternating stack extends along a first horizontal direction; each electrically conductive layer other than the at least one first drain-select-level electrically conductive layer and the at least one second drain-select-level electrically conductive layer laterally extends along the first horizontal direction between, and is laterally bounded by, a first backside trench and a second backside trench that laterally extend along the first horizontal direction; and one or more of the at least one first drain-select-level electrically conductive layer and the at least one second drain-select-level electrically conductive layer laterally extend along the first horizontal direction between, and are laterally bounded by, the first backside trench and a dielectric isolation structure located between, and laterally spaced from, the first backside trench and the second backside trench.
