Abstract

An energy efficient memory and logic device for the post-CMOS era has been the goal of a variety of research fields. The limits of scaling, which we expect to reach by the year 2025, demand that future advances in computational power will not be realized from ever-shrinking device sizes, but rather by innovative designs and new materials and physics. Magnetoresistive based devices have been a promising candidate for future integrated magnetic computation because of its unique non-volatility and functionalities. The application of perpendicular magnetic anisotropy for potential STT-RAM application was demonstrated and later has been intensively investigated by both academia and industry groups, but there is no clear path way how scaling will work for both memory and logic applications. One of main reasons is that there is no demonstrated material stack candidate that could lead to a scaling scheme down to sub 10 nm. Another challenge for the usage of magnetoresistive based devices for logic application is its available switching speed and writing energy. Although a good progress has been made to demonstrate the fast switching of a thermally stable magnetic tunnel junction (MTJ) down to 165 ps, it is still several times slower than its CMOS counterpart. In this talk, I will review the challenges and discuss the opportunities and some potential path ways for magnetoresitive based devices for memory, logic and sensing applications and their integrations. By end of my talk, I will brief introduce C-SPIN center and its activities too. 

Biography

Jian-Ping Wang is the Centennial Chair and a Distinguished McKnight University Professor of Electrical and Computer Engineering, and a member of the graduate faculty in Physics, Chemical Engineering and Materials Science and Biomedical Engineering at the University of Minnesota. He received his PhD degree in 1995 from Institute of Physics, Chinese Academy of Sciences, where he performed research on nanomagnetism. He established and managed the Magnetic Media and Materials program at Data Storage Institute, Singapore, as the founding program manager, from 1998 to 2002. He joined the faculty of the Electrical and Computer Engineering department at the University of Minnesota in 2002 and was promoted to full professor in 2009. He is the director of the Center for Spintronic Materials, Interfaces and Novel Architectures (C-SPIN). He received the information storage industry consortium (INSIC) technical award in 2006 for his pioneering work in exchange coupled composite magnetic media and the outstanding professor award for his contribution to undergraduate teaching in 2010. He has authored and co-authored more than 210 publications in peer-reviewed top journals and conference proceedings and holds 34 patents. He has been performing pioneering research on exchange coupled composite perpendicular media, perpendicular spintronic devices and magnetic tunnel junction based memory, logic and computation devices. His current research programs focus on searching, fabricating and fundamentally understanding novel nanoscale magnetic and spintronic materials and devices.
