data remanence

[nexxter]

Hi Folks

I an looking for some documentation about data remanence (eeprom, flash).  I am working on a little speech about risks on read/write process and not following manufacturers guidelines. 

I have seen some papers online with possibilities on bad erase, but those are not really usable. 

is there any paper available?

thanks a lot

Hi Jun

I am refering to MC9S12XE chip Family, highly used in controller units. 

I know there are a large number of "theoretical" fails based on data remanence, overwriting, false erasing, ....   but would need any kind of paper just to look at it.
