The passage around this formula
…the completeness of the other five that one should exist. He named the missing element the memristor and gave it a defining relation: . where M(q) , the memristance, depends on the history of charge q that has flowed through the device — which is precisely what makes a memristor’s resistance a record of its own past, and precisely why it was recognized decades later as a natural candidate for an analogue, in-memory synaptic weight [ 3 ] .
