I have read in a Microchip datasheet for a 24LC256 that the minimun data retention life is in the order of 100,000 R/W cycles. I assume this would be similar for the onboard data EEPROM in PICs?
Any ideas what the write ONCE, read many, (WORM) life expectancy would be. My project will write an eeprom full of data at program time and that's it, except for reading various locations once every second or so.
100,000 is only a day and half, nowhere near long enough.
I assume that this is a physical material type of attribute rather than anything to do with programming etc, so using RAM would still suffer from the same if it is made from similar materials???
I would need a life of a couple of years at least.

(Hope this isn't really in the wrong forum, but I am programming with PBP!)
