Patent ID: 7120049

Claim:
A magnetic memory comprising: a plurality of word lines; a plurality of bit lines; a plurality of magnetic cells; and a plurality of selecting elements, each of the magnetic cells being connected to one of the word lines and to one of the bit lines via one of the selecting elements, recording or reproduction with a specific magnetic cell being made possible by selecting one of the word lines and one of the bit lines, and each of the magnetic cells having: a first ferromagnetic layer whose magnetization is substantially fixed in a first direction; a second ferromagnetic layer whose magnetization is substantially fixed in a second direction opposite to the first direction; a third ferromagnetic layer provided between the first and the second ferromagnetic layers, a direction of magnetization of the third ferromagnetic layer being variable; a first intermediate layer provided between the first and the third ferromagnetic layers; and a second intermediate layer provided between the second and the third ferromagnetic layers, the direction of magnetization of the third ferromagnetic layer being determined under an influence of spin-polarized electrons upon the third ferromagnetic layer by passing a current between the first and the second ferromagnetic layers.
