According to one embodiment, a device includes transistors each with a path connected to a bit line, and circuits each includes a switch, the circuit being connected to the bit line. The device includes a amplifier connected to the transistor and to the circuit, and a latch connected to the amplifier to hold first data before read is carried out on a cell and to hold second data if a current equal to or a larger than a predetermined value flows via the bit line. In the device, the switch is turned on or off depending on data held in another latch located adjacently in a direction of the word lines, to control a connection between the bit line and connected to another bit line the amplifier via the circuit.
