EEPROM

Updated: 04/26/2017 by Computer Hope

Short for electrically erasable programmable read-only memory, EEPROM is a PROM that can be erased and reprogrammed using an electrical charge. EEPROM was developed by George Perlegos while at Intel in 1978 and unlike most memory inside a computer, this memory remembers data when the power is turned off.

AMIBIOS BIOS

EEPROM was a replacement for PROM and EPROM chips and is used for later computer's BIOS that were built after 1994. Having a computer with an EEPROM allows a computer user to update the BIOS in their computer without having to open the computer or remove any chips.

Where is the ROM on a computer?

For the computer, the main EEPROM and BIOS is on the computer motherboard.

Note

Other expansion cards and devices may have their own EEPROM or ROM on them as well.
