Sorry, but I could not resist... :)

Flash ROM or Flash Eprom (as You say), or F.EPROM ==>  FEPROM is a
natural upgrade from EEPROM, see? a step up in the letters... :)   It is
a complete different technology, Flash is faster to read/write, Eeprom
stands more writes before it gets compromised (Eeprom = around 1 million
cycles, Flash = 1 thousand cycles), Flash is easier to produce for large
arrays and memory size, Eeprom is older. Actual  both devices generate
internally the higher voltage necessary to write the cells, so actual
devices uses only +5V and +3.3V (I guess), didn't see anything for +2.5V
yet.  Technical details?  well, eeprom change (programs) a "funnel"
characteristic into a silicon cell, while flash use a "floating cell"
... :) both are very sensible to data mess up when detonating a small
neutron bomb close to it.... oh man... don't press it too hard...
