I don't know if this is what Anders was getting at, but there are some
EEPROMs that have an SRAM shadow that you can pound on all day at full
speed, then when the voltage starts to dip when power goes away they burn
the flash cells. (Kinda like the X2212, but automatic.)
Not sure if that's how the Xicor 28HC64's work or not? I suspect they write
data on the fly, but use an SRAM page cache to get rid of the latency.
Suppose I could actually go read the datasheet. I don't know if they have
the low-voltage memory protect like the 48Z02 (SRAM) or not...
