Working Principles

The AT34C04-X5M-B is based on EEPROM technology, which utilizes floating-gate transistors to store digital information. When a byte of data needs to be written, an electrical charge is applied to the floating gate, trapping electrons and altering the transistor's behavior. This change can be detected during subsequent read operations.
