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 18):
The method of  claim 17 , further comprising:\n forming a third vertical NAND string extending through the alternating stack, the third vertical NAND string comprising a third drain region and third memory cell charge storage transistors in a series connection with a fifth drain select transistor and a sixth drain select transistor; forming a fourth vertical NAND string extending through the alternating stack, the fourth vertical NAND string comprising a fourth drain region and fourth memory cell charge storage transistors in a series connection with a seventh drain select transistor and an eighth drain select transistor; forming a third separate drain select gate electrode connected to the sixth drain select transistor; and forming a fourth separate drain select gate electrode connected to the eighth drain select transistor, wherein:\n the common drain select gate electrode is formed such that the common gate drain select gate electrode is shared between the fifth drain select transistor and the seventh drain select transistor; and \n the first separate drain select gate electrode, the second separate drain select gate electrode, the third separate drain select gate electrode, and the fourth separate drain select gate electrode are formed so as to be not electrically connected to each other.
