Abstract
A spin-orbit torque magnetoresistive random-access memory device formed by fabricating a spin-Hall-effect (SHE) layer above and in electrical contact with a transistor, forming a spin-orbit-torque (SOT) magnetoresistive random access memory (MRAM) cell stack disposed above and in electrical contact with the SHE rail, wherein the SOT-MRAM cell stack comprises a free layer, a tunnel junction layer, and a reference layer, forming a cylindrical diode structure above and in electrical contact with the SOT-MRAM cell stack, forming a write line disposed in electrical contact with the SHE rail, and forming a read line disposed above and adjacent to an outer cylindrical electrode of the diode structure.
