Abstract
Integrating magnetic random access memory with logic is disclosed. The magnetic tunnel junction stack of a magnetic memory cell is disposed within a dielectric layer which serves as a via level of an interlevel dielectric layer with a metal level above the via level. An integration scheme for forming dual damascene structures for interconnects can be formed to logic and memory cells easily.
