Working Principles

The 93C76BT-I/SN EEPROM IC utilizes a floating gate transistor structure 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 through electrical signals, allowing the transistor to return to its original state and enabling data erasure. The stored data can be read by applying appropriate voltage levels to the IC's pins.
