Abstract
A method and system for providing and using a magnetic memory including magnetic memory cells is disclosed. The method and system include providing a magnetic tunneling junction including a first ferromagnetic layer, a second ferromagnetic layer and an insulating layer between the first ferromagnetic layer and the second ferromagnetic layer. The magnetic memory cell is coupled to a merged word line and a bit line. The merged word line selects the magnetic memory cell during a reading and carries a write current for the magnetic memory cell during writing. The bit line provides current to the magnetic memory cell during the reading and the writing. The currents provided by the bit line and the merged word line during writing allow data to be written to the magnetic memory cell.
