Abstract
A random code generator includes a differential cell array, a power circuit, a voltage detector, a control circuit and a read/write circuit. The power circuit provides a supply voltage to a node. The differential cell array includes plural differential cells. Each differential cell includes two sub-cells. The two sub-cells have process variations. During the enrollment, one sub-cell is programmed, and the other sub-cell is subjected to a program inhibition. In addition, a random code is generated according to the storage state of the differential cell.
