Ah... I did not know that 3.3V FRAMs were substantially longer-lived
than the original 5V versions. I'm still in favor of a pair of 62256s
(since they are so common and very cheap), but if I were to do an FRAM
board in the future, it's probably worth the extra buffers and
regulator to get chips that will last.
