Ah, I hadn't made the connection between FLASH drives and Flash
EEPROMS. However, this pushes the question back: how would an
EEPROM do it? Old PROMs used to burn fuses to maintain state, but how
to restore state, eh?
I believe that one could make flash drives that start at all-1s and
then burn the 0s into the memory. A small battery-powered device
could maintain the address of the next writable word, otherwise once
the device reached the end of memory, it would no longer be useful
for. writing.
Anyway, cheers!
