Patent ID: 7381573

Claim:
A method of forming a memory array structure, the method comprising: forming a plurality of memory cell structures, each of the memory cell structures formed by: forming a trench in a first insulating material to define at least one recess, forming a ferromagnetic cladding material within the at least one recess such that the ferromagnetic cladding material has at least one recess, forming a first conductive material within the recess of the ferromagnetic cladding material such that the first conductive material has a recess, forming a second insulating material within the recess of the first conductive material such that the second insulating material has a recess, forming a second conductive material within the recess of the second insulating material, and forming a magnetic tunnel junction element over the second conductive material; and forming a third conductive material over at least two adjacent magnetic tunnel junction elements of the plurality of memory cell structures.
