INVERTED WIDE BASE DOUBLE MAGNETIC TUNNEL JUNCTION DEVICE

Abstract:

A method of manufacturing a double magnetic tunnel junction device is provided. The method includes forming a first magnetic tunnel junction stack, forming a spin conducting layer on the first magnetic tunnel junction stack, and forming a second magnetic tunnel junction stack on the spin conducting layer. The second magnetic tunnel junction stack has a width that is greater than a width of the first magnetic tunnel junction stack.
