  • Patent number: 10991877
    Abstract: A multi-state memory and a method for manufacturing the same. A magnetoresistive tunnel junction is disposed on a spin-orbit coupling layer, and thermal annealing is performed after dopant ions are injected from a side of the magnetoresistive tunnel junction.

Symmetry along the direction perpendicular to the direction of the current is broken. In a case a current flows into the spin-orbit coupling layer, resistance are outputted in multiple states in linearity with the current. The multi-state storage is achieved. It can meet a requirement on hardware of neural network synapses, and is applicable to calculation in a neural network.
