Abstract:
1. A spin memory comprising: a magneto-resistance element having a first ferromagnetic layer in which a magnetization direction is pinned, a second ferromagnetic layer in which a magnetization direction changes, and a first nonmagnetic layer therebetween; a lower electrode and an upper electrode extending in a direction from 45 degrees to less than 90 degrees relative to an axis of hard magnetization of the second ferromagnetic layer, and sandwiching the magneto-resistance element between one end of a longitudinal direction of the lower electrode and one end of a longitudinal direction of the upper electrode; a switching element which is connected to another end of the longitudinal direction of the lower electrode, which turns on during changing of the magnetization direction of the second ferromagnetic layer to flow a write current between the lower electrode and the upper electrode through the magneto-resistance element, and the changing being executed by the write current to supply spin-polarized electrons to the second ferromagnetic layer and by a magnetic field which is generated by the write current flowing between the lower electrode and the upper electrode; and a bit line connected to another end of the longitudinal direction of the upper electrode.
