I don't have my Dallas Semi book handy, but if I remember correctly

the shelf life of the

Stored charge is involved, but not quite in a
If one is concerned with this one can often take the EPROM out, insert in
programmer, read it, erase it (if not OTP) and then re-program it for another
life cycle.
It is not the EPROM has a life, but the stored info has a finite time it is
held or stored.
Some EPROMs have the capability of loc
Richard,
All EEPROMs have a finite life to maintain their programmed info. The earlier
ones were in the months time frame (this is in the 70s) and were used for
development only.
Later in the 80s most were up to 10 years. Today 40 years is common. It is
not a factor of the device going bad
Eric,
As Kevin said if your 96 has one of the Dallas Smartwatch the battery in some
of them had a life of 10 years. It was basically the shelf life of the battery.
Most of the Smartwatch's I've seen used a RAM as the memory rather than a
EPROM. The battery maintained the memory when power was
