A semiconductor memory device includes first conductive layers arranged in a first direction, second conductive layers arranged in the first direction, a first semiconductor layer disposed therebetween, a charge storage layer, a first wiring electrically connected to the first semiconductor layer, and first and second transistors connected to the first and the second conductive layers. In the semiconductor memory device, in an erase operation, a first voltage is supplied to at least a part of the first conductive layers, an erase voltage larger than the first voltage is supplied to the first wiring, and a first signal voltage is supplied to at least a part of the second transistors. The first signal voltage turns OFF the second transistor.
