Questions tagged [eeprom]

Anything related to Electrically-Erasable Programmable Read Only Memory (EEPROM), a kind of non-volatile electronic memory technology. EEPROMs can be programmed and erased using only electrical signals and maintain their content also in absence of power supply. The now ubiquitous Flash memory is a specialized form of EEPROM.
