Abstract
A random code generator includes a power source, a sensing circuit, a first memory cell and a second memory cell. A first terminal of the first memory cell is connected with the power source. A second terminal of the first memory cell is connected with the sensing circuit. A first terminal of the second memory cell is connected with the power source. A second terminal of the second memory cell is connected with the sensing circuit. The power source provides a supplying voltage to both the first memory cell and the second memory cell during an enrollment. A random code is then determined according to the resistance difference between the first memory cell and the second memory cell after the enrollment.
