RE: HP-48 FRAM Cards
I still am not quite clear on the read/write cycles. While there may be more than 10 billion times the number of cycles as FLASH (according to an earlier post), what exactly happens during a read cycle? Does the entire content of FRAM get re-written? Or just the bits that got read? What happens when FRAM gets mapped to parts that get read frequently? For example, if the display data is mapped onto FRAM, then there are lots of read/write cycles without the user ever doing anything but having their calculator on. Can someone comment on this?
