Hello,
I am not sure where to post this, maybe in the General Electronics Discussion? Please let me know

Is it possible to electrically erase, an EEPROM, at a specific byte or set of bytes?

I have read that one can electrically erase entire EEPROM. Also, if one wants to erase a specific byte(s), then one would have to write FFh at a specific address. I haven't seen if it is possible to electrically erase at a specific byte(s).

Thanks,
F

Why do you want to erase a byte?
You can simply write anything you wish at that location unless the specific EEPROM only allows you to write zeros.
In general, you have to erase the byte in order to write data that has ones unless the bit was already a 1.
Check the EEPROM datasheet.
