Zusammenfassung:A semiconductor memory device is provided that includes a plurality of memory blocks, arranged in a second direction, that are spaced from a semiconductor substrate in a first direction intersecting with a surface of the semiconductor substrate; a first wiring that is farther from the semiconductor substrate than the plurality of memory blocks in the first direction; a second wiring that is closer to the semiconductor substrate than the plurality of memory blocks in the first direction; a first contact; a first transistor with a first active region disposed in the semiconductor substrate, the second wiring being electrically connected to a first memory block among the plurality of memory blocks via the first transistor; and a second transistor where the second wiring being electrically connected to a second memory block among the plurality of memory blocks via the second transistor.
