Magnetic random-access memory

Abstract

The present disclosure provides a magnetic random-access memory, comprising: an antiferromagnetic layer; a magnetic tunnel junction disposed on the antiferromagnetic layer and comprising a ferromagnetic layer disposed corresponding to the antiferromagnetic layer; wherein the ferromagnetic layer of the magnetic tunnel junction has in-plane magnetic anisotropy, and an exchange bias field is formed between the antiferromagnetic layer and the ferromagnetic layer by an annealing process. A direction of the exchange bias field is changed by a spin orbit torque, thereby changing a direction of a magnetic moment of the ferromagnetic layer and realizing data writing. The present disclosure can improve a thermal stability of the i-MTJ and reduce a lateral dimension of the i-MTJ, thereby improving a storage density of the magnetic memory.
