Biorealistic spiking neural networks (SNN) are believed to hold promise for further energy improvement over artificial neural networks (ANNs). However, it is difficult to implement SNNs in hardware, in particular the complicated algorithms that ANNs can handle with ease. Thus, it is natural to look for a middle path by combining the advantages of these two types of networks and consolidating them using an ANN–SNN converter. A proof‐of‐concept study of this idea is performed by experimentally demonstrating such a converter using diffusive memristor neurons coupled with a 32×1 1‐transistor 1‐memristor (1T1R) synapse array of drift memristors. It is experimentally verified that the weighted sum output of the memristor synapse array can be readily converted into the frequency of oscillation of an oscillatory neuron based on a SiO_xN_y:Ag diffusive memristor. Two converters are then connected capacitively to …
