Zusammenfassung:The present disclosure provides a magnetic random access memory structure, including an array region, and a logic region adjacent to the array region. The logic region includes a bottom electrode via, a magnetic tunneling junction layer over the bottom electrode via, a top electrode over the MTJ, a conformable oxide layer over the MTJ and the top electrode, and a silicon oxide layer over the conformable oxide layer. The conformable oxide layer and the silicon oxide layer extend from the array region to the logic region.
