Life expectancy of EEPROM
How many "write" cycles is the EEPROM on a Stamp good for? Millions? Billions? Forever?
I've tried finding the information, but can't find that key parameter.

Thanks -- I'm fairly new to this particular collection of hardware.
Is there an easy (meaning, on the order of "READ" and "WRITE" easy) PBASIC way to access a serial SRAM that's connected to some collection of I/O pins? My application updates several words of EEPROM memory once a second and I'd prefer for the devices I'm prototyping to be good for more than 11 days before reaching that "at least 1,000,000" limit. A small serial SRAM would do the trick.
I intend to eventually do a full-on custom PIC, but the Stamps will get me through hardware prototyping (and with serial SRAM, early hardware release) in the meantime.

RTC chips aren't RAM enough, although having a clock on board might be handy. Something else I can add to my growing list of "Things I'm going to MUX/DEMUX along the way."
(And battery backup is something I hope to avoid -- these devices are going to be monitoring power systems. If they don't have electricity, they have far bigger problems.)
32K is probably more than I could ever hope to use, but my brain is already thinking of uses!

My first computer had 1KB of RAM. I've used "small" before, and I can code in "small" fairly well. But having owned PCs with as much as 16GB of RAM, I'm tired of "small".
