What seems the most likely is that, effectively, memory is like very lossy, probabilistic compression spread with redundancy across a billion analog storage nodes, similar in some ways to a Bloom filter. It’s not binary though, it’s analog. After all, there’s no value in perfectly “unlearning” or destroying a specific memory, just “free” it up by gradual deemphasis of its parts and perhaps it may effectively go away.Also, the interplay between short-term and long-term memory formation in order to make some approximation of the short-term memory (also an approximation) somewhat permanent.
Granted, recall is imperfect and different every each time.

Still, one can memorize and recall some things with almost perfect accuracy (at least over time), for example phone numbers.
