Working Principles

The AT24C04N-10SC chip utilizes a combination of floating gate transistors and electrically isolated gates to store and retrieve data. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during the erase process, allowing the transistor to return to its original state. The stored data can be accessed by applying appropriate voltage levels to the address and control pins.
