The atomic switch marked a beginning of a new paradigm, namelynanoelectronics achieved by ions, which was succeeded in the derivative technologies: memristorand resistive random access memory. In conventional semiconductor technology, ions had longbeen nothing but troublesome impurities causing unstable operations; however, they are nowplaying a leading role in next-generation information and communication technology.Masakazu Aono (Director-General, MANA) and his co-workers invented the atomic switch and havebeen developing the technology with several researchers at MANA/NIMS for about 10 years incollaboration with NEC Corp. Now, the atomic switch has come into practical use as the “NECAtomSW-FPGA (Atomic Switch-Field Programmable Gate Array),” which will soon be used in robotsand space satellites.To celebrate the practical use of the atomic switch, a memorial symposium will be held. At thesymposium, speakers will present information about how the atomic switch has begun to be usedfor brain-type information processing and for completely novel functional nanodevices as well. Thissymposium will be useful for all scientists and engineers who are interested in nanoscale devices inrelation to AI and IoT. Participation in this symposium is strongly encouraged.
