    摘要： A non-volatile semiconductor storage device 10 has a plurality of memory strings 100 with a plurality of electrically rewritable memory transistors MTr1-MTr4 connected in series. The memory string 100 includes a columnar semiconductor CLmn extending in a direction perpendicular to a substrate, a plurality of charge accumulation layers formed around the columnar semiconductor CLmn via insulating films, and selection gate lines on the drain side SGD contacting the columnar semiconductor to configure transistors. The selection gate lines on the drain side SGD have lower selection gate lines on the drain side SGDd, each of which is arranged with an interval with a certain pitch, and upper selection gate lines on the drain side SGDu located on a higher layer than the lower selection gate lines on the drain side SGDd, each of which is arranged on gaps between the lower selection gate lines on the drain side SGDd.
