  • Patent number: 9886989
    Abstract: The present disclosure concerns a magnetic random access memory (MRAM) cell suitable for performing a thermally assisted write operation or a spin torque transfer (STT) based write operation, comprising a magnetic tunnel junction comprising a top electrode; a tunnel barrier layer comprised between a first ferromagnetic layer having a first magnetization direction, and a second ferromagnetic layer having a second magnetization direction adjustable with respect to the first magnetization direction; a front-end layer; and a magnetic or metallic layer on which the second ferromagnetic layer is deposited; the second ferromagnetic layer being comprised between the front-end layer and the tunnel barrier layer and having a thickness comprised between about 0.5 nm and about 2 nm, such that magnetic tunnel junction has a magnetoresistance larger than about 100%. The MRAM cell disclosed herein has lower power consumption compared to conventional MRAM cells.
