Working Principles

The AT24C02-10TI-1.8 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." This mechanism allows for non-volatile data storage and retrieval.
