Abstract
According to one embodiment, a semiconductor memory device includes a substrate, a stacked body, a plurality of columnar portions, and a first interconnect. When an imaginary first straight line extending in a second direction crossing a first direction is set, the plurality of columnar portions are divided into first sets of n (n is an integer number not less than 3 and not more than 32) columnar portions with center axes alternately disposed on both sides of the first straight line along the second direction and second sets of n columnar portions having position relationships of inversion of the first sets with respect to the first straight line, and the first sets and the second sets are alternately arranged.
