Patent ID: 7176065

Claim:
A method of forming an MRAM device comprising: simultaneously forming a plurality of first layers of magnetic material on a semiconductor substrate, wherein at least one of the first layers of magnetic material is for an antifuse device and at least a second one of the first layers of magnetic material is for a memory cell; simultaneously forming a plurality of dielectric layers on the plurality of first layers of magnetic material wherein at least one of the dielectric layer is for the antifuse device and at least a second one of the dielectric layers is for the memory cell; simultaneously forming a plurality of second layers of magnetic material on a plurality of the dielectric layers wherein at least one of the second layers of magnetic material is for the antifuse device and at least a second one of the second layers of magnetic material is for the memory cell; and electrically interconnecting the antifuse device to a source of electrical potential such that application of the electrical potential results in the antifuse device being shorted.
