Abstract:
1. A magnetic memory device comprising: first and second write wires that intersect each other in a non-contact manner; and a magnetic tunnel junction element which is arranged in an intersection of said first and second write wires and includes a magnetic tunnel junction, wherein said magnetic tunnel junction element has a free layer consisting of a ferromagnetic material in which a magnetization direction is variable with a magnetic field generated by current flowing through said first and second write wires, and in the case where a distance between a center of said first write wire in a thickness direction and a center of said free layer in the thickness direction is represented as L a distance between a center of said second write wire in the thickness direction and a center of said free layer in the thickness direction is represented as L a cross-sectional area of said first write wire in a width direction is represented as S a cross-sectional area of said second write wire in a width direction is referred to as S said distance L when a ratio of said distance L a relation of (⅓)·(L when the ratio of said distance L a relation of 1≦S
