Abstract

A magnetic memory according to an embodiment includes: a magnetoresistive device including a first magnetic layer, a second magnetic layer, and a first nonmagnetic layer between the first magnetic layer and the second magnetic layer; a first wiring electrically connected to the first magnetic layer; a second wiring that is electrically connected to the second magnetic layer and contains an antiferromagnetic material; a third wiring crossing the second wiring; an insulating layer between the second wiring and the third wiring; a first write circuit for applying a voltage between the second wiring and the third wiring; and a read circuit electrically connected to the first wiring and the second wiring.
