Abstract
According to one embodiment, a semiconductor memory device includes a stacked body, first memory portions, and second memory portions. The stacked body includes conductive layers. The conductive layers are arranged in a first direction and extend in a second direction. The stacked body includes first and second regions. The second region is arranged with the first region in the second direction. The first memory portions extend in the first direction through the first region and are arranged at a first pitch along the second direction. The second memory portions extend in the first direction through the second region and are arranged at the first pitch along the second direction. A distance between a first center of one of the first memory portions and a second center of one of the second memory portions is longer than the first pitch and shorter than 2 times the first pitch.
