By EN 25F80 EEPROM problem EON
   In some eeprom in the many outstanding mpeg dvd in Indonesia, one of which is made by EON SILICON SOLUTION.Inc.Contohnya type EN or EN 25F80 25D80.
In the article 25F80 EN copier, here we revise as well as providing new information to readers who have made a series copier, that: Especially for this type eeprom (EN 25F80) can only be read (read) and written (write) once only. ( once write / programming)
So in this case you can only save the data to back up files * e2p. or * bin. from normal eeprom for eeprom then you should find a new (empty) to the rewrite.
If at any time you re-write (write / programming) these eeprom, there was an error, this is common, because EON made specifically for this type eeprom OTP = One Time Programming.
Copier is not problematic if used to read and write eeprom re-made again on other manufacturers (ST, windbond, AT etc.).
But no one we always berexperimen, because experience is the most valuable teacher.
Hopefully helpful, greeting success always ...
