Working Principles

AT93C86-10SC utilizes a floating gate transistor technology 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 read by applying appropriate voltage levels to the chip's pins.
