In summary, employing in silico calculations we proposed, designed, and provided a proof-ofconcept of the function of a molecular spinristor, which is a circuit component reported neither in the realm of molecular nor macroscopic electronics, to the best of our knowledge. The spinristor behaves like a combination of a spin filter and a rectifier at low voltages. At higher voltages, the polarity of the rectifier switches akin to a memristor by the relocation of the encapsulated metal ion. Our design utilizes M@C70 molecules connected to four electrodes, source, drain, and a pair of gate electrodes to improve the switching function. The spin-filtering
