Abstract
An approach to provide a structure of a double magnetic tunnel junction device with two spacers that includes a bottom magnetic tunnel junction stack, a spin conducting layer on the bottom magnetic tunnel junction stack, a top magnetic tunnel junction stack on the spin conduction layer, a first dielectric spacer on sides of the top magnetic tunnel junction stack and a portion of a top surface of the spin conduction layer, and a second dielectric spacer on the first spacer. The double magnetic tunnel device includes the top magnetic tunnel junction stack with a width that is less than the width of the bottom magnetic tunnel junction stack.
