Working Principles

The 34AA02-E/ST utilizes EEPROM technology to store digital information. It employs a floating gate transistor structure that allows for non-volatile storage of data. When a byte of data needs to be written, an electric charge is applied to the floating gate, altering its electrical characteristics. This change in charge determines the stored data value. During read operations, the stored charge is measured, allowing the retrieval of the stored data.
