Abstract
A semiconductor storage device includes a plurality of conductor layers that are stacked in a first direction and a plurality of bit lines that are spaced from each other in a second direction. Pillars extend in the first direction through the conductor layers and are electrically connected to the bit lines. An insulator is provided that divides the region in which the plurality of pillars are disposed into adjacent regions. An interval between the pillars in an end row adjacent to the insulator is greater than an interval between the pillars in an inner row that is not directly adjacent to the insulator.
