It depends on the EEPROM.  Some older EEPROMS can be written some thousands
of times.  I've seen data sheets that specify tens or hundreds of thousands
of writes for newer EEPROMS.  I believe the number of writes to an EEPROM
is heavily temperature dependant, but I'm not sure.

I think you'll be fine unless you write a bunch of times every day.

It's also worth pointing out that EEPROMS eventually lose the charge that
keeps the data on the chip.  I've seen this time measured in 10+ years.  I
often wonder if EEPROMS in older machines will eventually bit rot and need
to be replaced.
