Abstract:
A magnetic memory comprising:a first magnetoresistance effect element having a magnetic recording layer; a first wiring extending in a first direction on or below the first magnetoresistance effect element; a covering layer provided on at least both sides of the first wiring, the covering layer being made of magnetic material, and a condition L1>(2L2+L3) being satisfied where L1 is a length of the covering layer along a lengthwise direction of the first wiring, L2 is a width of the covering layer provided on the both sides of the first wiring, and L3 is a width of the covering layer provided on an upper or lower side of the first wiring; and a writing circuit configured to pass a current through the first wiring in order to record information in the magnetic recording layer by a magnetic field generated by the current.
