ABSTRACT:
A semiconductor device includes a memory portion in which a plurality of magneto-resistance effect elements each having a hard-axis of magnetization and an easy-axis of magnetization are arranged and one of binary data is written in all the magneto-resistance effect elements, and a circuit portion to which a write current is supplied to write only the other one of the binary data in only a selected magneto-resistance effect element selected from the magneto-resistance effect elements.
