Recent Advances in MRAM Technology

In this paper we review recent progress, present specifics of Freescale's commercial MRAM device, and discuss the future outlook for MRAM technology, including the extension of Toggle MRAM to meet industrial/automotive requirements, and scaling behavior to the reduced dimensions of advanced technology nodes. We have performed extensive operational characterization and accelerated stress testing of our extended-range MRAM technology and validated its full functionality and high reliability in these extreme environments. In conclusion, recent progress demonstrates the ability of Toggle MRAM to meet industrial and automotive requirements. New research results on higher-performance materials and devices show the potential for advanced scaling and further performance improvements in both read and write properties.
