Abstract
To provide a magnetic memory for storing multi-level information capable of reading while sufficiently securing a read margin. Provided is a magnetic memory including: first and second magnetic storage elements that are provided between a first wiring and a second wiring crossing each other, and are electrically connected in series; a third wiring electrically connected between the first and second magnetic storage elements; a first determination unit that determines a magnetization state of the first magnetic storage element on the basis of a current flowing to the first magnetic storage element through the third wiring; and a second determination unit that determines a magnetization state of the second magnetic storage element on the basis of a current flowing to the first and second magnetic storage elements through the first wiring, in which the determination state of the second determination unit is changed on the basis of the determination result of the first determination unit.
