Abstract

A memory includes first cell layers respectively including first cells, and a second cell layer including dummy cells. A first wire is connected to the first cells arrayed in a first direction. A second wire is connected to the dummy cells arrayed in the first direction. A third wire is connected to the first cells and one of the dummy cells arrayed in a second direction. A fourth wire is connected to the third wires arrayed in a third direction. A first voltage is applied to a selected first wire when reading data from a selected first cell, and transmits a read data to a selected fourth wire connected to the selected first cell. A reference voltage is applied to a non-selected fourth wire. A second voltage is applied to a selected second wire provided with the dummy cell between the selected second wire and the non-selected fourth wire.
