Magnetic memory with self-aligned magnetic keeper structure |
摘要 |
A magnetic tunneling junction (MTJ) memory cell is formed with a keeper structure on its upper conductor (write line). The keeper structure is formed by a self aligned process as three pieces: two vertical soft magnetic side pieces contacting an upper soft magnetic layer. The structure so formed completely surrounds an upper conductor and terminates on a horizontal extension of the MTJ sense layer.
