Abstract
A semiconductor storage device includes a substrate, a plurality of conductive layers arranged in a first direction intersecting a surface of the substrate, and a semiconductor layer extending in the first direction and penetrating the plurality of conductive layers. The plurality of conductive layers includes a first conductive layer and a second conductive layer that are adjacent to each other, a third conductive layer and a fourth conductive layer that are adjacent to each other, and a fifth conductive layer and a sixth conductive layer that are adjacent to each other. When a distance between the first conductive layer and the second conductive layer in the first direction is a first distance, a distance between the third conductive layer and the fourth conductive layer in the first direction is a second distance, and a distance between the fifth conductive layer and the sixth conductive layer in the first direction is a third distance, the second distance is smaller than the first distance, and the third distance is smaller than the second distance.
