Working Principles

The 24LC1026T-I/ST utilizes EEPROM technology, which allows for the storage of digital information in a non-volatile manner. It uses an array of floating-gate transistors to store and retrieve data. When data is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erasure process, allowing the transistor to return to its original state.
