Digital readout optimization of the random resistive states in magnetic tunnel junction

Abstract

True random number generators (TRNGs) provide a wide area of applications and can be fabricated on the basis of magnetic tunnel junctions (MTJs). This work represents the modeling of TRNG readout optimization, where the induced digital random bit is detected within only a single computational period. The period contains two sub-cycles: write and joined read & reset cycles. The system has a valuable potential to become stochastically independent after calibrating at the desired working point against the factors, which cause to the signal deviations: temperature-induced, material degradation or other problems.
