Abstract
A storage device according to embodiments includes a substrate, a stacked body, a first region, a second region, and first to nth electrodes. The stacked body is provided on the substrate and having first to nth (n is an integer of 3 or more) conductive layers stacked in a direction perpendicular to a surface of the substrate. The first region includes a part of the stacked body, and has a first step structure including the first to the nth conductive layers. The second region includes a part of the stacked body, and has a second step structure different from the first step structure including at least a part of the first to nth conductive layers. The first to nth electrodes are provided in the first region and connected to the first to nth conductive layers and extend in a direction perpendicular to the surface of the substrate.
