Abstract
A three-dimensional integrated circuit non-volatile memory array includes a memory array of vertical channel NAND flash strings connected between a substrate source line and upper layer connection lines which each include n-type drain regions and p-type body line contact regions alternately disposed on each side of undoped or lightly doped string body regions so that each NAND flash string includes a vertical string body portion connected to a horizontal string body portion formed from the string body regions of the upper body connection lines.
