Claim 0:
1. A semiconductor storage device, comprising:
a stacked structure in which a plurality of conductive layers is stacked in a stacking direction via an insulating layer;
a plurality of pillars extending in the stacking direction in the stacked structure and including a memory cell formed at an intersection between at least a part of the plurality of conductive layers and at least a part of the plurality of pillars;
a plurality of first contacts arranged in the stacked structure, each of the first contacts reaching a different depth in the stacked structure and being connected to a conductive layer in a different layer among the plurality of conductive layers; and
a plurality of second contacts arranged in the stacked structure separately from the plurality of first contacts, each of the second contacts reaching a different depth in the stacked structure and being connected to a conductive layer identical to the conductive layer to which a corresponding one of the plurality of first contacts is connected.
