Claim 12:
13. A semiconductor storage device, comprising:
a substrate;
a first stack including a plurality of first conductive layers and a plurality of first insulating layers alternately stacked in a first direction intersecting a surface of the substrate, the first stack extending in a second direction parallel to the surface of the substrate;
a first semiconductor layer extending through the first stack in the first direction;
a second stack including a plurality of second conductive layers and a plurality of second insulating layers alternately stacked in the first direction, the second stack extending in the second direction, the first and second stacks being adjacent in a third direction parallel to the surface of the substrate;
a second semiconductor layer extending through the second stack in the first direction;
a first structure extending in the first and second directions, the first structure between the first and second stacks in the third direction;
a third semiconductor layer above the first and second stacks and electrically connected to the first and second semiconductor layers; and
a third conductive layer in physical contact with an upper surface of the third semiconductor layer, a part of the third conductive layer being in physical contact with the first structure.
