Bad Eeprom write on '628???

[BobK]

Hi Keith,

Something has been bugging me for several years after reading about the lifetime of an EEPROM. Is the lifetime determined by how many times you write to the EEPROM as a whole or is it per location of the EEPROM? Just curious.

Thanks,

BobK

Dunno is the short answer.

It might be limited to blocks of memory because I have see mention of moving the location where you store data after x number of writes to get a longer lifetime.

EG 4 times the memory size so you use the first quarter then move the the second quarter etc.

Hopefully someone with more experiece of EEPROM will give a better answer
