Abstract:
A semiconductor memory device according to an embodiment includes a first stacked body, a second stacked body, an intermediate conductive layer, an intermediate insulating layer, a semiconductor pillar, a charge storage film, and an insulating film. The semiconductor pillar includes a first part, a second part, and a third part. The charge storage film includes a first charge storage portion and a second charge storage portion. The charge storage film includes at least one first element selected from the group consisting of nitrogen, hafnium, and aluminum. The insulating film provides in at least a portion between the intermediate conductive layer and the first part. The insulating film not includes the first element, or the insulating film has a concentration of the first element lower than a concentration of the first element of the charge storage film.

Claim (Index 1):
A semiconductor memory device, comprising:\n a stacked body including\n a first stacked unit and a second stacked unit stacked above the first stacked unit, each of the first and second stacked units including a plurality of first electrode layers alternately stacked with a plurality of first insulating layers therebetween, and \n a first intermediate layer provided above the first stacked unit and below the second stacked unit, a thickness of the first intermediate layer being greater than a thickness of the first insulating layers; \n a semiconductor pillar piercing the stacked body in a stacking direction of the stacked body, the semiconductor pillar including a first semiconductor film portion covering an outer periphery of a first core insulator part extending in the a first stacked unit and a second semiconductor film portion covering an outer periphery of a second core insulator part extending in the a second stacked unit, the first semiconductor film portion and the second semiconductor film portion having asymmetric configurations with respect to the first intermediate layer; a first charge storage film provided between the first semiconductor film portion and one part of the first electrode layers included in the first stacked unit; and a second charge storage film provided between the second semiconductor film portion and another part of the first electrode layers included in the second stacked unit, wherein the first semiconductor film portion is electrically connected to the second semiconductor film portion via a third semiconductor film portion provided in the first intermediate layer, and the first charge storage film is discontinuous with the second charge storage film.
