Abstract:
According to one embodiment, a semiconductor memory device includes a plurality of first interconnects extending in a first direction, a plurality of second interconnects extending in a second direction, a plurality of stacked films respectively provided between the first interconnects and the second interconnects, each of the plurality of stacked films including a variable resistance film, a first inter-layer insulating film provided in a first region between the stacked films, and a second inter-layer insulating film provided in a second region having a wider width than the first region. The second inter-layer insulating film includes a plurality of protrusions configured to support one portion of the plurality of second interconnects on the second region. A protruding length of the protrusions is less than a stacking height of the stacked films.

Claim (Index 9):
A semiconductor memory device, comprising:\n a first interconnect including tungsten extending in a first direction; a second interconnect including tungsten extending in the second direction crossing the first direction; a third interconnect including tungsten extending in the second direction, and the third interconnect being arranged apart from the second interconnect in the first interconnection; a first layer including nitride being provided on the first interconnect, and the first layer extending in the first direction; a first stacked film being provided between the first interconnect and the second interconnect in a third direction crossing to the first direction and the second direction, the first stacked film including a first variable resistance film; a second stacked film being provided between the first interconnect and the third interconnect in the third direction, the second stacked film including a second variable resistance film; a first insulating film being provide between the first stacked film and the second stacked film in the first direction, the first insulating film extending in the third direction; and a second insulating film including nitride, in a cross sectional view perpendicular to the first direction, the second insulating film being provided, between the first stacked film and the first insulating film in the first direction, between the first layer and the first insulating film in the third direction, and between the second stacked film and the first insulating film in the first direction.
