Claim 18:
19. The method of claim 16, wherein the time-varying resistance device is a spin-orbit torque (SOT) tuned magnetic tunnel junction (MTJ) device comprising a spin-orbital coupling (SOC) layer; a top barrier layer disposed on the SOC layer; a free ferromagnetic layer disposed on the top barrier layer; a tunneling barrier layer disposed on the free ferromagnetic layer; a reference ferromagnetic layer disposed on the tunneling barrier layer, wherein the free ferromagnetic layer is more magnetically isotropic than the reference ferromagnetic layer, or the reference ferromagnetic layer is more magnetically anisotropic than the free ferromagnetic layer; positive and negative bias terminals are coupled to the SOC layer; a first voltage input terminal is coupled to the free ferromagnetic layer; and a second voltage input terminal is coupled to the reference ferromagnetic layer, and wherein the method further comprises:
applying a current to the positive or the negative bias terminals, wherein:
the applied current flows between the positive and negative bias terminals to bias the free ferromagnetic layer according to a mean of the probability distribution, and
a magnetoresistance is created between the positive voltage input terminal and the negative voltage input terminal based on the bias of the free ferromagnetic layer, and the probabilistic resistance value is based on the magnetoresistance.
