I certainly agree with the "borderline art territory" effect.

I wonder if a MOSFET with a low-leakage cap on the gate would hold a charge
long enough (for some values of "long enough"; I'm thinking hours or days)
to be usefully considered as "memory".  Add a refresh circuit to make it
"somewhat permanent".

Your agreeing to maybe use core makes it hard to tell just what you want to
model.  I guess anything that's nonvolatile.  Come to think of it, you're
having the same "hard time" the original guys were having in the 1970's.
