Abstract
A semiconductor storage device includes first conductive layers stacked in a first direction and extend in a second direction; second conductive layers stacked in the first direction and extend in the second direction; third conductive layers that are electrically connected to the first conductive layers and the second conductive layers and stacked in the first direction; a first insulating layer and a second insulating layer sandwich the first conductive layer; a third insulating layer and a fourth insulating layer sandwich the second conductive layer; first pillars arranged in the second direction in the first insulating layer with a first distance; and second pillars arranged in the second direction in the second insulating layer with the first distance. Each of the second pillars is displaced from a corresponding one of the first pillars by a second distance that is shorter than a half of the first distance in the second direction.
