    Abstract: A random code generator includes a differential cell array, a power supply circuit, a first selecting circuit and a current judgment circuit. The power supply circuit receives an enrolling signal and a feedback signal. The first selecting circuit receives a first selecting signal. When the enrolling signal is activated and an enrollment is performed on the first differential cell, the power supply circuit provides an enrolling voltage, and the enrolling voltage is transmitted to a first storage element and a second storage element of the first differential cell through the first selecting circuit. Consequently, the cell current is generated. When a magnitude of the cell current is higher than a specified current value, the current judgment circuit activates the feedback signal, so that the power supply circuit stops providing the enrolling voltage.
