That would be 'no', then? :)

Hallo Donald,

there are so many different flash families on the market and such heavy change and developement, that mechanism I told about can already be antiquated, today.

I wanted to focuse, that stress due to very high electric field is so extreme, that a predictable behaviour normaly cannot be expected at end of lifetime. It's important to note, that memory cell gets totally destroyed at end of lifetime, in a sense, that doping concentration and resistivity is highly affected. But how knows, may be memory cells are becoming fabricated in future, such that kind of destruction becomes predictable?

I think only a close contact to manufacturer can finally answer this question.

Regards,
Kai
