Abstract

See full text

A spin-orbit torque magnetoresistive random-access memory device formed by fabricating a first electrode upon a conductive contact of an underlying semiconductor device, forming a first vertical magnetoresistive random-access memory (MRAM) cell stack upon the first electrode, forming a spin-Hall-effect (SHE) layer above and in electrical contact with the MRAM cell stack, forming a protective dielectric layer covering a portion of the SHE layer, forming a second vertical MRAM cell stack above and in electrical contact with an exposed portion of the SHE layer, forming a second electrode above and in electrical contact with the second vertical MRAM cell stack, and forming a metal contact above and in electrical connection with the second electrode.
