Abstract:
A method and system for providing a magnetic memory are described. The method and system include providing magnetic storage cells, bit lines coupled with the magnetic storage cells, preset lines, and word lines coupled with the magnetic storage cells. Each magnetic storage cell includes magnetic element(s). The bit lines drive write current(s) through selected storage cell(s) of the magnetic storage cells to write to the selected storage cell(s). The preset lines drive preset current(s) in proximity to but not through the selected storage cell(s). The preset current(s) generate magnetic field(s) to orient the magnetic element(s) of the selected storage cell(s) in a direction. The word lines enable the selected storage cell(s) for writing. Either the bit lines reside between the preset lines and the storage cells or the preset lines reside between the storage cells and on a storage cell side of the bit lines.
