Abstract
A semiconductor memory device includes a substrate, conductive layers arranged in a first direction and extend in a second direction, a semiconductor layer extending in the first direction and opposed to the conductive layers, and n contact electrode regions arranged in a third direction. The n is a power of 2. The contact electrode region includes contact electrodes arranged in the second direction. The conductive layers include a first conductive layer and a second conductive layer that is an n-th conductive layer counted from the first conductive layer. The contact electrodes include a first contact electrode connected to the first conductive layer, a second contact electrode connected to the second conductive layer, and a third contact electrode disposed between them. The first contact electrode, the second contact electrode, and the third contact electrode are arranged in the second direction or the third direction.
