Abstract
According to one embodiment, a semiconductor storage device includes: a first select transistor connected at a first end of a memory string; a second select transistor connected at a second end of the memory string; and a controller. In a write operation of writing data into a first memory cell transistor of the memory string, the controller performs: a first operation of applying a first voltage to a gate of the first memory cell transistor, while turning on the first and second select transistor; and a second operation of applying a second voltage higher than the first voltage to the gate of the first memory cell transistor, while turning off the first and second select transistor; and the second operation is performed after the first operation.
