Abstract
A volatile memory area includes a plurality of second memory cells, a third select transistor, and a fourth select transistor. The plurality of second memory cells are electrically connected in series, and stacked above the substrate. The third select transistor is connected to one end of the plurality of second memory cells, and connected to a second bit line. The fourth select transistor is connected to the other end of the plurality of second memory cells, and unconnected to a second source line. A controller is configured to supply a first voltage to all gates of the second memory cells. The first voltage is capable of turning on the plurality of second memory cells.
