Working Principles

The AT28C16E-15PC utilizes a floating-gate transistor structure to store and retrieve data. When programming, an electric charge is applied to the floating gate, altering its electrical characteristics. This change determines whether the corresponding memory cell represents a logical "0" or "1". Erasing the chip involves removing the charge from the floating gates, resetting the memory cells to their initial state.
