Кому-то на пользу, кому-то - вред. Вот в SAML10/L11 делают Trust
RAM и механизмы для предотвращения "замерзания" / “burnin”. The
TRAM can execute two automated tasks that are triggered by external
events: remanence prevention and erase. When a remanence periodic
event occurs, the physical data stored in the RAM is inverted to
prevent physical “burnin” signatures.
