I believe there is a functional definition of amnesia, loss of factual memory, life skills remain intact. I guess I would call what you are calling a memory wipe a "brain wipe". I guess I'd call what you are calling memory "total brain content". If a brain is wiped of all content in the forest is Usul's idea of consciousness spared? No idea. Total brain reboot? I'd say yes and call that good as dead I think.

I would say probably yes to the text only question. Again, loss of factual memory. But I don't rate that as a reliable or valid test in this context.
