Abstract
A magnetic memory device includes first to third conductors and a 3-terminal type memory cell coupled to the first to third conductors. The memory cell includes: a fourth conductor and a magnetoresistance effect element provided between the fourth and third conductors. The magnetoresistance effect element includes: a first ferromagnet in contact with the fourth conductor; a second ferromagnet provided in an opposite side of the fourth conductor with respect to the first ferromagnet; a dielectric between the first and second ferromagnets; a third ferromagnet provided in an opposite side of the first ferromagnet with respect to the second ferromagnet; and a nonmagnet provided between the second and third ferromagnets. A concentration of a noble metal contained in the first ferromagnet is higher than a concentration of the noble metal contained in the second ferromagnet.
