Abstract
A method for writing to a magnetic memory comprising: providing a plurality of magnetic tunnel junctions arranged into columns and rows, applying a first current to a first conductive line coupled to a row of magnetic tunnel junctions at their ends adjacent to a free ferromagnetic layer to produce a bias magnetic field; and applying a second current to a second conductive line electrically coupled to a column of magnetic tunnel junctions at their ends adjacent to a pinned ferromagnetic layer to produce a spin momentum transfer in the free ferromagnetic layer of a first magnetic tunnel junction disposed at a first intersection region formed by the first conductive line and the second conductive line; wherein a joint effect of the first and second currents applied simultaneously reverses a magnetization direction of the free ferromagnetic layer of the first magnetic tunnel junction. Other embodiments of the magnetic memory are disclosed.
