Abstract
A semiconductor memory device includes first conductive layers stacked in a first direction. A bit line is above the first conductive layers in the first direction. A second conductive layer and a first insulating layer are between the first conductive layers and the bit line. A first pillar extends through the first conductive layers and the second conductive layer. A first via contact connected to an end of the first pillar is on a bit line side. The distance between an upper end of the first insulating layer and an upper surface of the second conductive layer is greater than or equal to the distance between an upper end of the first via contact and the upper surface of the second conductive layer.
