One of the things that can make a eeprom go "bananas to the beat"
is when one excedes the cyckling limmit, or the "write" limmit of the
eeprom.
Usually the data retendention time of 10 years at -40c to +85(120)c
(which in practice aprox minimum 40 years or more at 25 degrees c)is not
the
issue of failure of the eeprom.

I have a ESQ1 since the day one it was available at the market 85/86 i
think it was,
and a home built eeprom card (aprox 14 years old now )from the same date
as the purcase
of the esq1,  without any loss of data in this eeprom.(and 10 thousands
of working ohurs)

You could infact out burn a eeprom in a week or soo by just writing
all the time to the eeprom!
