Abstract
A semiconductor memory device including: plural first conductive layers stacked on a substrate; plural second conductive layers each stacked between the first conductive layers; a pillar that extends in a stacking direction of the first and second conductive layers and forms plural memory cells at intersections of the first and second conductive layers in a region where first and second conductive layers are arranged; a first contact plug that extends in the stacking direction of the first and second conductive layers and is connected to the first conductive layers in the region where the first and second conductive layers are arranged; and a second contact plug that extends in the stacking direction of the first and second conductive layers and is connected to the second conductive layers in the region where the first conductive layers and second conductive layers are arranged.
