EEPROM

Updated: 09/12/2023 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, it remembers its data without power.

AMIBIOS BIOS

EEPROM was a replacement for PROM (programmable read-only memory) and EPROM (erasable programmable read-only memory) chips and is used for later computer's BIOS (basic input/output system) that were built after 1994. Having a computer with an EEPROM allows the user to update the computer's BIOS without opening the computer or removing 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 an EEPROM or ROM (read-only memory) on them as well.
