Hi,
There is a problem in the customer's board.
The contents of Flash has changed.
A bit in Flash has changed from 0 to 1.
(Region not program)
Here was a question from the customer.
How does Flash's contents change when the charge is removed in Flash memory?
"0" to "1" or "1" to "0"?
I decided the answer from "0" to "1".
Is that understanding?
Regards, DA
As shown in section 2 of the application report, in an erased (1) cell, the floating gate has a positive charge, and in a programmed (0) cell, the floating gate has a negative charge.
However, according to Wikipedia, an erased cell is uncharged, so I guess the application report means positive compared to the programmed state.
Anyway, section 3.1.2 says that
single bit failures due to leakage currents show erroneous 0s that should be 1s. These single bit failures based on leakage currents can never read erroneous 1, instead of expected 0s.
There does not appear to be a hardware error mechanism that would result in a 0 → 1 error.
