MAGNETIC RANDOM ACCESS MEMORY CELL WITH IMPROVED DISPERSION OF SWITCHING FIELD Russian patent published in 2016 - IPC G11C11/15 G11C11/16 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering. Magnetic random access memory (MRAM) cell comprises a tunnel magnetic junction having the first ferromagnetic layer, the second ferromagnetic layer with the second magnetization, which can be oriented relative to the axis of anisotropy of the second ferromagnetic layer at a predetermined high-temperature threshold, and a tunnel barrier between the first and the second ferromagnetic layers; the first current transmission line extending along the first direction and being in communication with the tunnel magnetic junction; herewith the first current transmission line is configured able to provide the magnetic field to orient the second magnetization while transferring the field current; wherein the MRAM cell is configured relative to the first current transmission line in such a way, that while providing the magnetic field at least one magnetic field component is perpendicular to the said axis of anisotropy; the second ferromagnetic layer is of asymmetric shape along at least one of its dimensions, so that the second magnetization contains the pattern of C-shape condition.

EFFECT: technical result is the reduction of power consumption and improved dispersion of the switching field.
