The first edition of the International Conference on Memristive Materials, Devices, and Systems (MEMRISYS) was held in Athens in April 2017. The aim was to consolidate at a single international conference on Memristor Technologies in the research communities in circuit theory, materials science, electronic devices, and neuromorphic computing. The 6th edition was held in Torino, Italy: while most of the contributions were about MEMRISYS core topics such as resistive switching mechanisms and in-memory computing, increased interest was recorded towards new device schemes (like 3-terminal ones), edge applications, and unconventional computing paradigms (such as reservoir computing).
