Working Principles

The 24LC1025-E/SN utilizes a combination of floating gate transistors and electronic charge injection 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 erasing process, allowing the transistor to return to its original state. The stored data can be accessed by applying appropriate voltage levels to the chip's pins.
