Working Principles

AT34C02N-10SC-2.7 utilizes EEPROM technology, which employs floating-gate transistors to store and retrieve data. When data is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erase operation, allowing the transistor to return to its original state. The stored data can be accessed by applying appropriate voltage levels to the memory cells.
