< storage > (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 EPROM s because reprogramming could be done with the chip installed. At that time FEPROMs could be rewritten about 1000 times.
Like EAPROM and ferro-magnetic material, FEPROMs rely on FN tunnelling . Some flash memory supports block erase.
