A semiconductor memory device according to an embodiment includes first to ninth conductive layers, first and second insulating members, and first to fourth pillars. A distance between the first and second pillars in a cross section including the second conductive layer and the sixth conductive layer is smaller than a distance between the first and second pillars in a cross section including the third conductive layer and the seventh conductive layer. A distance between the third and fourth pillars in a cross section including the fourth conductive layer and the eighth conductive layer is greater than a distance between the third and fourth pillars in a cross section including the fifth conductive layer and the ninth conductive layer.
