(FEPROM, "flash memory") A kind of {non-volatile storage} device similar to {EEPROM}, but where erasing can only be done in blocks or the entire chip. In 1995 this relatively new technology started to replace href="module.php?name=Lexikon&file=search&eid=1&query=EPROM">EPROMs because reprogramming could be done with the chip installed. At that time FEPROMs could be rewritten about 1000 times. Like href="module.php?name=Lexikon&file=search&eid=1&query=EAPROM">EAPROM and ferro-magnetic material, FEPROMs rely on {FN tunnelling}. Some flash memory supports block erase. (1995-04-22)
