Thanks for the links about holographic storage, they're interesting.
An "associative network" has the property that is similar to holographic
memory: it can produce a previously activated pattern when provided
with a cue. Maybe thats what you're talking about.
Memory in the human brain also appear to work similarly - "priming".
But associated recall is not the only thing that the brain does, so it
might not be the _universal_ mechanism that you seem to claim it is.
