Abstract
According to one embodiment, a semiconductor storage device includes a first wiring, a first resistance change element which is connected to the first wiring, a first nonlinear element which is connected to the first resistance change element, and a second wiring which is connected to the first nonlinear element. In a read operation for the first resistance change element, a voltage between the first wiring and the second wiring increases to a first voltage, and after the voltage between the first wiring and the second wiring increases to the first voltage, the voltage between the first wiring and the second wiring increases to a second voltage which is larger than the first voltage.
