Abstract
The present disclosure concerns memory device comprising magnetic tunnel junction comprising a tunnel barrier layer between a first ferromagnetic layer having a first magnetization with a fixed orientation and a second ferromagnetic layer having a second magnetization being freely orientable, and a polarizing layer having a polarizing magnetization substantially perpendicular to the first and second magnetization; the first and second ferromagnetic layers being annealed such that a tunnel magnetoresistance of the magnetic tunnel junction is equal or greater than about 150%. Also disclosed is a method of forming the MRAM cell.
