Figure 2From: Neuromorphic crossbar circuit with nanoscale filamentary-switching binary memristors for speech recognitionAnalog memristors with interface-switching mechanism and binary memristors with filamentary-switching mechanism. (a) Analog memristor with the interface-switching mechanism [10, 11], where the memristance value can be changed gradually from LRS to HRS, and (b) binary memristor with the filamentary-switching mechanism [12–17], where the memristance value can be changed very abruptly between LRS and HRS.Back to article page
