Abstract
A magnetic memory storage device with at least one magnetic storage element comprising electrical addressing leads to inject electrical current directly through a single magnetic memory storage element. The number of electrical addressing leads is at least one more than the number of magnetic memory storage elements.
Claims7
A method of addressing digital data, comprising the steps of:
- (a) directing an unpolarized electrical current directly by electrical contact through a first addressing line of a device wherein the device comprises 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 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;
- and
- (b) monitoring the change in voltage across a sense line containing the addressing line.
