Daniel	Worledge

Daniel Worledge



Dr. Worledge received a BA with a double major in Physics and Applied Mathematics from UC Berkeley in 1995, receiving the Department Scholar Award in physics and the Dorothea Klumpke Roberts Prize in mathematics. He then received a PhD in Applied Physics from Stanford University in 2000, with a thesis on spin-polarized tunneling in oxide ferromagnets, measuring the largest tunneling spin-polarization in (LaSr)MnO3 and the first negative tunneling spin-polarization in SrRuO3. After joining the Physical Sciences Department at the IBM T. J. Watson Research Center as a Post-doc in 2000, he became a Research Staff Member in 2001, inventing and developing Current-in-Plane Tunneling as a fast turn-around measurement method for magnetic tunnel junctions.

In 2003, Dr. Worledge became the manager of the MRAM Materials and Devices group, and in 2013 he became Senior Manager of MRAM. In 2014 he was promoted to Principle Research Staff Member and in 2015 to Distinguished Research Staff Member. He has worked on developing Toggle and then Spin Torque MRAM, including discovering perpendicular magnetic anisotropy in Ta|CoFeB|MgO, and leading the IBM team that developed perpendicular magnetic tunnel junctions and demonstrated the first integrated perpendicular spin torque MRAM, with ultra-low bit error rate. His current research interests include magnetic devices and their behavior at small dimensions, and new magnetic devices for logic applications. Dr. Worledge has received three IBM Outstanding Technical Achievement Awards and the IBM Research Client Award.
