Hafnium Oxide Based Ferroelectric FET Non-volatile Memory

Associate Professor Vita Pi-Ho Hu
National Central University, Taiwan

Artificial intelligence (AI) and Internet-of-Things (IoT) play a vital role in the future. For the von Neumann architecture, communication bottleneck between memory and processors becomes one of the most series problems due to low data throughput and high-power consumption. Non-volatile memory (NVM) based synapse and logic-in-memory circuit have been proposed to alleviate these problems. Ferroelectric Field-Effect-Transistor (FeFET) has been explored actively for emerging non-volatile memory and neuromorphic computing due to its high compatibility with CMOS platform. In this talk, I will introduce the operation principles of FeFET. We have proposed a novel split-gate FeFET (SG-FeFET) for non-volatile memory and neuromorphic applications, which significantly improves the energy efficiency and reduces the power consumption. The results of this work have been accepted for presentation in the top conference 2019 Symposia on VLSI Technology & Circuits held in Kyoto, Japan in June.

Vita Pi-Ho Hu received the B. S. degree in materials science and engineering and the Ph.D. degree in electronics engineering & institute of electronics from National Chiao Tung University, Hsinchu, Taiwan in 2004 and 2011, respectively. Her research interests include emerging memory, Silicon and IIIV-based nanoelectronics, and ultra-low power SRAM and logic circuits using emerging devices. She was an intern at TSMC from 2004 to 2007. From 2011 to 2015, she was an assistant research fellow with National Chiao Tung University. She has authored or coauthored over 100 refereed journal and conference papers regarding her research interests. She has received the Outstanding Student Paper Award 1st Place Winner at the 2011 IEEE International Conference on IC Design and Technology (ICICDT), the Postdoctoral Research Award from Taiwan Semiconductor Industry Association (TSIA) in 2014, Best Paper Award in IEEE International Symposium on the Physical and Failure Analysis of Integrated Circuits (IPFA) in 2015, Excellent Young Researcher Project Award from Ministry of Science and Technology (MOST) in 2016, Exploration Research Award of Pan Wen Yuan Foundation in 2017, Excellent Teaching Award of the EECS College in NCU in 2018, and MOST Young Scholar Fellowship in 2018. Dr. Hu joins National Central University, Taiwan as an tenure-track assistant professor in 2015.
