光电信息大讲堂第三十七讲：关于忆阻器，你所不知道的 10 件事

报告摘要：

本讲座将回答大众及研究人员所疑问的忆阻器理论中的10个基本问题：什么是忆阻器？忆阻器的判据？物理忆阻器件与理想忆阻器的差异？直流激励下理想忆阻器伏安曲线为线性的“点”？交流激励下忆阻器却展现出捏滞回线？忆阻器的捏滞回线为何与激励的幅值、频率和初始态有关？如何从忆阻器的断电图判断其易失性？状态连续和分立的非易失性存储器的差异？局域无源忆阻器和局域有源忆阻器的概念？为何我们认为大脑也是由忆阻器构成的？

What is a Memristor? What are the fingerprint and signature of memristors? How does a real-world memristor device differ from an ideal memristor? Why does the DC V-I characteristics of an ideal memristor consist of only “one point”? Why does the AC V-I characteristics of all memristors consist of a family of pinched hysteresis loops? How does the pinched hysteresis loop of a memristor depend on the amplitude, frequency, and initial condition? How does the POP (Power-Off Plot) of a memristor determine whether it is a non-volatile or volatile memory device? What is the difference between a continuum and a discrete non-volatile memory? What is the difference between a locally-passive memristor and locally-active memristor? Why are brains made of memristors?

The answer to the above questions and other FAQ will be given in this talk.

Often introduced as the father of the tiger mother, Leon Chua is the inventor of the memristor, Chua Circuit, and Cellular Nonlinear Networks (CNN). He is also known as the father of Nonlinear Circuit Theory. A fellow of the IEEE since 1975, Dr. Chua has been conferred 16 Honorary Doctorates from major universities worldwide. He has received numerous awards, including the first IEEE Kirchhoff Award, the Terman Award, a Guggenheim Fellow, and the European Union Marie-Currie Fellow. Dr. Chua is a member of the European Academic of Science and of the Hungarian Academy of Science.
