1. A magnetic memory comprising:
- a magnetoresistance effect element having a magnetic recording layer;
a first wiring extending in a first direction on or below the magnetoresistance effect element;
a covering layer provided at least both sides of the first wiring, the covering layer being made of magnetic material, and the covering layer having a uniaxial anisotropy in the first direction along which a magnetization of the covering layer occurs easily; and
a writing circuit configured to pass a current through the first wiring in order to record an information in the magnetic recording layer by a magnetic field generated by the current.

12. A magnetic memory comprising:
-
a first wiring extending in a first direction;
a magnetoresistance effect element provided on the first wiring and having a magnetic recording layer;
a second wiring extending in a direction across the first direction on the magnetoresistance effect element;
a covering layer provided on at least both sides of at least one of the first and second wirings, the covering layer being made of magnetic material, and the covering layer having a uniaxial anisotropy in a lengthwise direction of the wiring on which the covering layer is provided, along the lengthwise direction a magnetization of the covering layer occurring easily; and
a writing circuit configured to pass currents through the first and second wirings in order to record one of two values of two-valued information in the magnetic recording layer by magnetic fields generated by the currents. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
