Abstract:
1. A device, comprising: (a) a first and a second magnetic element having a closed magnetization configuration, wherein said first and second magnetic element comprises multiple layers of magnetic and non-magnetic materials; and (b) a first electrical addressing lead to inject a first unpolarized electrical current directly by electrical contact to a first non-magnetic metal connector for writing or reading an individual element's magnetization state, a second electrical addressing lead to inject a second unpolarized electrical current directly by electrical contact to a second non-magnetic metal connector for writing or reading an individual element's magnetization state, wherein said first non-magnetic metal connector connects to said first magnetic element and wherein said second non-magnetic metal connector connects to said second magnetic element and a third non-magnetic metal connector connects to said first and said second magnetic elements and includes a third electrical addressing lead and wherein said first unpolarized electrical current is different from said second unpolarized electrical current.
