Right you are. I'm not really sure what that battery is doing, since this is non-volatile memory. It's interesting that the specification sheet says (about the battery):
"if the lithium is exhausted for any reason, the ROM can still be read
normally."
Apparently, the battery is only needed if you are changing the contents - because of the two-step programming process.

I have looked into this one
The Battery
is not related to programming it is because this kind of I-button has NVM (internal SRAM) - this holds the memory of SRAM and another oscillator , my assumption is that if battery is dead this key will not work any more
Thanks,
