A memristor circuit that can store, maintain and compare the activation of objects in the long‐term memory of a cognitive architecture is described. Objects accessed frequently or recently are assigned a high activation and are more likely to be retrieved first in a search that returns multiple matches. By using memristance to store the activation values, the circuit achieves high density and fast retrieval.
