"cryogenic CMOS memory controllers/ control interfaces rely on charge-current-driven spin-orbit torques, generating excessive Joule heating exceeding cooling budgets of sub-kelvin cryostats... overcome eliminating high-current magnetic switching, instead utilizing voltage-controlled magnetic anisotropy across ferroelectric interface, achieving deterministic magnetization reversal.. memory's thermal load reduced several orders of magnitude... fault-tolerant quantum computer high-density memory"
