Working Principles

The 24AA128-I/SM EEPROM utilizes electrically isolated floating gate transistors to store and retrieve data. When a write operation is performed, an electric charge is applied to the floating gate, altering its threshold voltage. This change allows the transistor to represent either a logical "0" or "1". During read operations, the stored charge is measured, determining the logic level of the bit.
