Working Principles

AT25080-10PC utilizes EEPROM technology, which employs a floating gate transistor structure to store and retrieve data. The memory cells consist of transistors that can be electrically programmed and erased. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during the erase process, allowing the cell to be rewritten.
