Abstract:
Systems, methods, and devices of the various embodiments provide both “string-sharing” drain select gate electrodes and “string-selective” drain select gate electrodes in vertical NAND strings. Various embodiments may provide two or more vertical NAND strings sharing a common drain select gate electrode while also having separate additional drain select gate electrodes not electrically connected across the two or more vertical NAND strings.

Claim (Index 17):
A method of making a memory device, comprising:\n forming an alternating stack of insulating layers and spacer material layers over a substrate, wherein the spacer material layers are formed as, or subsequently replaced with, electrically conductive layers; forming a first vertical NAND string extending through the alternating stack, the first vertical NAND string comprising a first drain region and first memory cell charge storage transistors in a series connection with a first drain select transistor and a second drain select transistor; forming a second vertical NAND string extending through the alternating stack, the second vertical NAND string comprising a second drain region and second memory cell charge storage transistors in a series connection with a third drain select transistor and a fourth drain select transistor;\n forming a first separate drain select gate electrode connected to the second drain select transistor; and \n forming a second separate drain select gate electrode connected to the fourth drain select transistor; and forming a common drain select gate electrode shared between the first drain select transistor and the third drain select transistor, wherein the first separate drain select gate electrode and the second separate drain select gate electrode are formed such that the first separate drain select gate electrode and the second separate drain select gate electrode are not electrically connected to each other.
