Patent ID: 7242047

Claim:
A magnetic memory comprising: a magnetoresistance element including a free magnetic layer; a first interconnection extending in a first direction obliquely to an easy axis of said free magnetic layer; a second interconnection extending in a second direction substantially orthogonal to said first direction; and a write circuit writing data into said free magnetic layer through developing a first write current on said first interconnection, and then developing a second write current on said second interconnection with said first write current turned on, wherein said free magnetic layer includes: first to N-th ferromagnetic layers, N being equal to or more than 4; and first to (N−1)-th non-magnetic layers, said i-th non-magnetic layer being disposed between said i-th and (i+1)-th ferromagnetic layers, i being any of natural numbers equal to or less than N−1, and wherein said free magnetic layer is designed so that antiferromagnetic coupling(s) between said j-th and (j+1)-th ferromagnetic layers is stronger than that between said first and second ferromagnetic layers, j being any of integers ranging from 2 to N−2.
