Abstract
A method of forming a NAND flash memory includes forming a conductive area in a substrate, the conductive area extending along a direction that is perpendicular to the direction along which NAND strings extend, the conductive area connecting terminals of NAND strings. Discrete contact areas in the conductive area are contacted by discrete contact plugs, each contact plug contacting a corresponding contact area in the conductive area.
