Working Principles

The CAT93C86LI-G utilizes EEPROM technology, which employs a floating-gate transistor structure to store and retrieve data. When data is written, an electrical charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erasing process, allowing new data to be written.
