Working Principles

The AT24C08BN-SH-T utilizes a floating-gate transistor structure to store data. When a voltage is applied, electrons are trapped in the floating gate, representing a logical "1." Conversely, when the voltage is removed, the absence of trapped electrons represents a logical "0." The stored data can be read, written, or erased by applying appropriate electrical signals.
