Zusammenfassung:An MRAM structure includes an MTJ, a top electrode contacts an end of the MTJ. The top electrode includes a top electrode upper portion and a top electrode lower portion. The width of the top electrode upper portion is larger than the width of the top electrode lower portion. A bottom electrode contacts another end of the MTJ. The top electrode, the MTJ and the bottom electrode form an MRAM.
