Working Principles

The CAT24C01YI-GT3 utilizes a floating gate transistor structure to store data. When programming or erasing, an electric charge is applied to the floating gate, altering its electrical characteristics. This change determines whether the transistor represents a logical "0" or "1". The stored data can be accessed by applying appropriate voltage levels to the address and control pins.
