ESSDERC 2019 Keynote – Review of promising devices for neuromorphic applications

Keynote title (tentative):

Review of promising devices for neuromorphic applications


Jong-Ho Lee, Seoul National University, KR


Artificial intelligence technology has attracted much attention in recent years, and progress of the technology is expected with the development of semiconductor technology. This talk focuses on synaptic mimic devices to realize artificial intelligence with semiconductor memory technology. These synaptic devices affect cognitive accuracy along with conductance quantization and architecture. Therefore, we will first discuss from the architectural point of view and examine the characteristics of candidates for various synapse devices being reported. In particular, we concentrate on synaptic imitation devices that creatively use the functions of several flash memory devices. Finally, we discuss what features synaptic devices should have for neuromorphic applications, and how neuromorphic technology will evolve.


Jong-Ho Lee received the Ph.D. degrees from Seoul National University, Seoul, in 1993 in electronic engineering. In 1994, he was with the School of Electrical Engineering, Wonkwang University, Iksan, Chonpuk, Korea. In 2002, he moved to Kyungpook National University, Daegu Korea, as a Professor of the School of Electrical Engineering and Computer Science. Since September 2009, he has been a Professor in the School of Electrical and Computer Engineering, Seoul National University (SNU), Seoul Korea. He has been director of Inter-University Semiconductor Research Center (ISRC) at SNU since January 2018. From August 1998 to July 1999, he was with Massachusetts Institute of Technology, Cambridge, as a postdoctoral fellow. He has authored or coauthored 259 papers published in refereed journals and about 400 conference papers related to his research and has been granted 99 patents in this area. Prof. Lee is IEEE Fellow and a Lifetime Member of the Institute of Electronics Engineers of Korea (IEEK). He has been served as a subcommittee member of several international conferences including IEDM, ITRS ERD member, a general chair of IPFA2011, and IEEE EDS Korea chapter chair. He received 30 awards for excellent research papers and research excellence.
