So, let's see--for a system powered on and writing once per microsecond

operation,
no?
But the Ramtron squib for the FM18L08 says:
"FRAM is known for high write-endurance. Until now, some applications
needed more cycles than FRAM could offer. No longer! The FM18L08 offers
virtually unlimited read/write cycles. You can now access each address
a
million times per second for hundreds of years with no wear out. "
So, is 10^14 an accurate figure?
Well I got it from this month's Circuit Cellar article on FRAMs,
which I happened to have open on my desk when this came up. I've not
checked any datasheets.

Don't FRAMs have a maximum write count?
Well yes, 10^14 writes! ;)
