| 1. A magnetic storage device comprising:
a memory cell array having magnetoresistance effect elements placed in a matrix;
a first write line extending along a first direction, current being supplied to flow in the first write line only in the first
direction;
a second write line extending along the first direction, current being supplied to flow in the second write line only in the
second direction opposite to the first direction;
a third write line extending along a third direction which is orthogonal to the first direction, the magnetoresistance effect
elements being placed where the first and third write lines cross and where the second and third write lines cross;
a first electrode provided between the first and third write lines;
a first plug connected to the first electrode and provided at a location apart from the first write line along the third direction;
a second electrode provided between the second and the third write lines; and
a second plug connected to the second electrode and provided at a location apart from the second write line along an opposite
direction to the third direction.
