Abstract
A semiconductor storage device includes a first stacked body, a second stacked body, a first division film, a second division film, and a plurality of discrete films. The a first stacked body includes first electrode layers stacked in a first direction. The second stacked body, above the first stacked body, includes second electrode layers stacked in the first direction. The second semiconductor layer is electrically connected to the first semiconductor layer. The first division film, extending in the first direction through the first stacked body, divides the first stacked body in a second direction crossing the first direction. The second division film, extending in the first direction through the second stacked body, divides the second stacked body in the second direction. The discrete films, extending in the first direction through the second stacked body, are disposed above the first division film.
