利用忆阻突触模仿巴甫洛夫条件反射对在硬件层次上实现神经形态计算具有重要意义。在这项工作中，我们展示了巴甫洛夫条件反射的基础上的人工突触架构的一个晶体管/一个电阻器（1 T1 R），其中包括一个AgInSbTe/α-C为基础的忆阻器作为可变电阻和N-MOS晶体管。由于忆阻器稳定的电阻开关行为和1 T1 R晶体管门控对器件电导的出色可控性，实现了巴甫洛夫条件反射的获取和消除的实验演示。此外，还建立了条件刺激与非条件刺激之间的时间关系，即联想学习的记忆时间随着两个刺激间隔的增加而减少。这项工作提供了一个想法，生物逼真地模仿巴甫洛夫条件反射，为忆阻神经形态计算铺平了道路。nbsp;由AIP Publishing独家授权出版。
Mimicking Pavlovian conditioning by memristive synapse is significant to implement neuromorphic computing at the hardware level. In this work, we demonstrated the Pavlovian conditioning based on the artificial synapse architecture of one-transistor/one-resistor (1T1R), which included an AgInSbTe/alpha-C-based memristor as a variable resistance and an N-MOS transistor. Thanks to stable resistance switching behavior of memristor and outstanding controllability of device conductance by transistor gating of 1T1R, the experimental demonstration of the acquisition and extinction of Pavlovian conditioning were realized. Moreover, the temporal relation between the conditioned and unconditioned stimuli was also established in which the memory time of associative learning decreased with the increase in the interval of two stimuli. This work provided an idea to biorealistically mimic the Pavlovian conditioning, paving the way for memristive neuromorphic computing.& nbsp;Published under an exclusive license by AIP Publishing.
