This paper examines the widespread Biolek and Pershin models of the memristor in order to find out whether they support STDP in an event-based computation environment. We find that they generally do not and proceed to examine a new model that does support this feature. Finally, we show data from physical devices confirming that the real devices do show the capability for STDP when driven by event-type signals. This is expected to impact the neuromorphic engineering community most, where well-behaved, practical synapse emulators are constantly sought.
