Abstract
An integrated circuit, wherein a voltage-adjustable power supply circuit () receives a first power supply control signal () output by a programming power supply control circuit (), outputs a first voltage signal to a efuse circuit () by a power source switching circuit () and outputs the first voltage signal to other functional circuits () of the integrated circuit, and the efuse circuit () receives the first voltage signal and a first programming control signal () output by the programming power supply control circuit () and burns out a corresponding efuse therein; or the voltage adjustable power supply circuit () receives a second power supply control signal () output by the programming power supply control circuit () and outputs a second voltage signal to other functional circuits () of the integrated circuit, and the efuse circuit () receives a second programming control signal () output by the programming power supply control circuit () and ensures a corresponding efuse therein not to be burnt out. Compared with the integrated circuit in the prior art, which integrates the effuse circuit (), the integrated circuit of the invention saves production cost and use cost and also saves the lead pin resources of the integrated circuit.
