Which solid-state storage technology allows a computer BIOS to be upgraded by flashing?

The solid-state storage technology that allows a computer BiOS to be upgraded by flashing is known as EEPROM (Electrically Erasable Programmable Read-Only Memory). EEPROM can retain data even when powered off and can be electrically erased and reprogrammed, making it suitable for storing firmware like the BiOS. This capability enables users to update their BiOS to improve system functionality or compatibility.
