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 8):
The memory device of  claim 6 , further comprising:\n a first dielectric core stack comprising a first lower dielectric core and a first upper dielectric core that are laterally surrounded by the first memory stack structure; and a second dielectric core stack comprising a second lower dielectric core and a second upper dielectric core that are laterally surrounded by the second memory stack structure; wherein: an upper region of the first lower dielectric core is doped with electrical dopants; and the first upper dielectric core, the second upper dielectric core, and the second lower dielectric core are substantially free of electrical dopants.
