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 13):
The memory device of  claim 1 , wherein:\n at least one first drain-select-level electrically conductive layer comprises multiple first drain-select-level electrically conductive layers; the first drain select transistor comprises a series connection of multiple component field effect transistors located at the levels of the multiple first drain-select-level electrically conductive layers; and each of the multiple component field effect transistors other than a bottommost one of the multiple component field effect transistors has a higher threshold voltage than the bottommost one of the multiple component field effect transistors.
