Abstract:
1. A magnetic memory comprising: a plurality of magnetic storage cells, each of the plurality of magnetic storage cells including at least one magnetic element; a plurality of bit lines coupled with the plurality of magnetic storage cells and being configured to drive at least one write current through at least one selected storage cell of the plurality of magnetic storage cells to write to the at least one selected storage cell; a plurality of preset lines for driving at least one preset current in proximity to but not through the at least one selected storage cell, the at least one preset current generating at least one magnetic field to orient the at least one magnetic element of the at least one selected storage cell in a direction; a plurality of word lines coupled with the plurality of magnetic storage cells and configured to enable the at least one selected storage cell for writing; wherein either the plurality of bit lines resides between the plurality of preset lines and the plurality of storage cells or the plurality of preset lines resides between the plurality of storage cells and on a storage cell side of the plurality of bit lines; wherein the plurality of preset lines is configured to start generating the at least one magnetic field before at least one write current starts being driven through the at least one selected storage cell, to stop generating the at least one magnetic field before the at least one write current starts being driven through the at least one storage cell and such that the at least one selected magnetic element has insufficient time to relax to an equilibrium state between the at least one magnetic field stopping being generated and the at least one write current starts being driven through the at least one selected storage cell.
