Synaptic potentiation and depression in Al:HfO2-based memristor
An Al:HfO2 memristor emulates the strength change observed in biological synapses. The memristor is self-compliant, so there is no need of external current limitation. A train of identical pulses is applied to the memristor to change its conductance. Pulses with proper voltagetime width gradually change the memristor conductance.
