Working Principles

The 24LC16BT-E/SN utilizes a floating gate transistor structure to store data. When programming, an electric charge is applied to the floating gate, altering its electrical characteristics. This change determines whether the corresponding memory cell stores a logical "0" or "1". Erasing the chip involves removing the charge from the floating gate, resetting the memory cells to their initial state.
