See also ds/3ds flash used in game carts. They need to be powered on every so often to avoid bitrot. Their memory controllers use a form of ecc that causes weak bits to be rewritten. But if it's left too long then ecc cannot correct. This is over 15-30 year timescale fwiw.
But all chips will die in like 50-100 years or so because physics gets em with electromigration.
