Working Principles

The 24LC1025T-I/SM utilizes EEPROM technology, which stores data using electrically isolated floating-gate transistors. When data needs to be written, an electrical charge is applied to the floating gate, altering its threshold voltage. This change in threshold voltage represents the stored data. Reading the data involves measuring the threshold voltage of the transistor.
