Abstract
A method and system for providing and using a magnetic random access memory are disclosed. The method and system include providing a plurality of magnetic memory cells, a first plurality of write lines, and a second plurality of write lines. The first plurality of write lines is a plurality of magnetic write lines. At least one of the plurality of magnetic lines and at least one of the second plurality of write lines each carrying a current for writing to at least one of the plurality of magnetic memory cells. Preferably, the plurality of magnetic write lines have soft magnetic properties and are preferably magnetic bit lines. For magnetic tunneling junction stacks within the magnetic memory cells, the magnetic bit lines are preferably significantly thicker than and closely spaced to the free layers of the magnetic memory cells.
