Antonyms for this word would refer to the absence of such memories, or the inability to recollect them. Some possible antonyms might include forgetting, amnesia, or memory loss. Alternatively, one might use terms like ignorance or unawareness to describe a lack of memories or knowledge about a particular subject.
