Working Principles

The AT24C08-10PC chip utilizes a combination of electrically erasable floating-gate transistors and a control circuitry to store and retrieve data. When data is written, the control circuitry applies a high voltage to the floating gate, trapping electrons and altering the transistor's behavior. This change in behavior represents the stored data. During read operations, the control circuitry detects the transistor's behavior and outputs the corresponding data.
