Does anyone know anything about programing a eeprom ? I have looking at a eeprom programmer. I was thinking if I could read the old one and transfer that data to the new eeprom. Would I be transferring bad data to a new device? The data is there, I'm wondering if it's a construction breakdown and the data is still good , anyone with any knowledge would be appreciated.
Many of us know a great deal about programming EEPROMs. I think with more specific information someone here should be able to provide some guidance.
But based on what you said above, if something is misbehaving due to issues reading an EEPROM, reading it out in an EEPROM programmer isn't likely to yield much benefit, as such devices access the chips in the same way they're accessed when in their operational device. There are other ways to get at that data, but would generally be considered impractical unless a great deal of time and money are available. (decapsulating chips, etc)
