Working Principles

The 24LC024-E/SN utilizes EEPROM technology, which employs a floating gate transistor structure to store and retrieve data. When data is written, an electrical charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erase process, allowing the transistor to return to its original state. The stored data can then be read by applying appropriate voltage levels to the chip's pins.
