Abstract
According to one embodiment, a storage device includes first wirings extending in a first direction and second wirings extending in a second direction. A memory cells are connected between the first wirings and the second wirings and include a variable resistance memory element. A first drive circuit is provided for supplying voltages to the first wirings, and a second drive circuit is provided for supplying voltages to the second wirings. The first drive circuit applies a first voltage to a selected first wiring, the second drive circuit applies a second voltage to a selected second wiring. A voltage between the second voltage and one-half of the sum of the first and second voltages is applied to a non-selected first wiring, and a voltage between the first voltage and one-half of the sum of the first and second voltages is applied to a non-selected second wiring.
