MAGNETISM RAM AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a magnetism RAM with high reliability and its manufacturing method, since shift and kink of switching magnetic field due to floating magnetic field can be prevented. SOLUTION: The magnetism RAM comprises a switching device and an MTJ cell coupled to the switching device, wherein the MTJ cell comprises a pinned film equipped with a metal film and a magnetic film enclosing the metal film.
