Abstract
Study of the reliability of ultra-thin MgO tunneling barriers for spin transfer switching magnetoresistive random access memory (MRAM) revealed MgO to be an excellent film with little resistance drift. Precise control of CoFeB/MgO/CoFeB interface was found to be important for making highly reliable tunneling barriers.
