The technology is mature and stable with low cost, so it is the mainstream in the application of electronic products in daily life. People use it in every way. In the fields of personal identity card, bank card, medical insurance card, traffic card and other smart cards, which are closely related to personal property, and in the field of communication system and other consumer electronic products such as PDA and digital camera, EEPROM is used. In instruments and other embedded systems, such as smart flowmeters, it is usually necessary to store information such as setting parameters, field data, etc., which requires that the system is not lost when it is powered down so that the data you originally set could be restored next time.
