Abstract
According to one embodiment, in a semiconductor memory device, the first chip has plural memory cells provided at plural intersection positions where the plural first conductive layers and the plural first semiconductor films intersect each other. The second chip has plural memory cells provided at plural intersection positions where the plural second conductive layers and the plural second semiconductor films intersect each other. A first connection configuration and a second connection configuration are insulated from each other. The first connection configuration reaches the third chip from a first conductive layer that a tip of the first semiconductor film reaches among the plural first conductive layers. The second connection configuration reaches the third chip from a second conductive layer that a tip of the second semiconductor film reaches among the plural second conductive layers.
