Abstract
According to one embodiment, a storage device includes a first conductor extending along a first direction, first variable-resistance elements on the first conductor, and a second conductor on the first variable-resistance elements and extending along a second direction. A plurality of second variable-resistance elements is on the second conductor. A third conductor is on the plurality of second variable-resistance elements. The third conductor extends along the first direction. A first switching element is connected between the second conductor and a corresponding one of the first variable-resistance elements. A second switching element is connected between the third conductor and a corresponding one of second variable-resistance elements.
