摘要: According to one embodiment, a semiconductor memory device includes plural magneto-resistance elements being two-dimensionally arrayed on a semiconductor substrate. In the semiconductor memory device, each of the magneto-resistance elements includes: a first magnetic layer formed on the semiconductor substrate; a non-magnetic layer formed on the first magnetic layer; and a second magnetic layer formed on the non-magnetic layer, and an insulating film buried between the magneto-resistance elements adjacent to each other, a powder made of a metallic material or a magnetic material being dispersed in the insulating film.
