Claim:
A magnetic memory, comprising a memory cell having: a first magnetic switching element including a first gate electrode; a first magnetic semiconductor layer which changes its state from a paramagnetic state to a ferromagnetic state by applying a voltage thereto; a first gate insulating film provided between the first gate electrode and the first magnetic semiconductor layer; and a first ferromagnetic layer provided between the first gate insulating film and the first magnetic semiconductor layer or provided on an opposite side of the first magnetic semiconductor layer from the first gate insulating film, the first ferromagnetic layer having a magnetization substantially pinned in a first direction, a magnetization corresponding to the magnetization of the first ferromagnetic layer being induced in the first magnetic semiconductor layer by applying a voltage from the first gate electrode to the first magnetic semiconductor layer through the first gate insulating film; a second magnetic switching element including a second gate electrode; a second magnetic semiconductor layer which changes its state from a paramagnetic state to a ferromagnetic state by applying a voltage thereto; a second gate insulating film provided between the second gate electrode and the second magnetic semiconductor layer; and a second ferromagnetic layer provided between the second gate insulating film and the second magnetic semiconductor layer or provided on an opposite side of the second magnetic semiconductor layer from the second gate insulating film, the second ferromagnetic layer having a magnetization substantially pinned in a second direction, a magnetization corresponding to the magnetization of the second ferromagnetic layer being induced in the second magnetic semiconductor layer by applying a voltage from the second gate electrode to the second magnetic semiconductor layer through the second gate insulating film; and a magnetoresistance effect element including a record layer made of a ferromagnetic material, a first magnetization being formed in the record layer by the magnetization induced in the first magnetic semiconductor layer in the first magnetic switching element, and a second magnetization being formed in the record layer by the magnetization induced in the second magnetic semiconductor layer in the second magnetic switching element.
