semantic memory

noun

: long-term memory of facts, information, and meanings that is not related to any specific event personally experienced in the past

Perhaps the most important distinction recently drawn is that between semantic memory (the memory for facts like that the Acropolis is in Athens) and episodic memory (the recall of events—those that happened to you, not those you've been told about).

—Stuart Sutherland, The New York Times Book Review
