A new nonvolatile hybrid memory cell is provided. The cell is comprised of a magnetic spin storage element and one or two semiconductor FET isolation elements. The magnetic spin storage element is an electron spin-based memory element situated on a silicon based substrate and includes a first ferromagnetic layer with a changeable magnetization state, and a second ferromagnetic layer with a non-changeable magnetization state. A current of spin polarized electrons has a magnitude which can be varied so that a data value can be stored in the memory element by varying a relative orientation of the two ferromagnetic layers.
