Abstract
A magnetic storage device includes a memory cell including a magnetoresistive effect element. The megnetoresistive effect element includes a storage layer and a reference layer. The magnetic storage device also includes a first line electrically coupled to a first terminal of the magnetoresistive effect element, a second line electrically coupled to a second terminal of the magnetoresistive effect element, and a write driver. The write driver supplies a first voltage to the first line in a first write operation in which a first resistance value of the magnetoresistive effect element is changed to a second resistance value smaller than the first resistance value, and supplies a second voltage different from the first voltage to the second line in a second write operation in which the second resistance value of the magnetoresistive effect element is changed to the first resistance value.
