A fuse circuit comprises a fuse set and an enable circuit. The enable circuit is configured to receive a test mode enable signal and a power up signal to generate an enable signal and a voltage level to the fuse set for indicating whether an external supply voltage reaches a predetermined value and whether a test mode is enabled. In particular, an output signal of the fuse set is constant in the test mode, regardless of whether a fuse in the fuse set is blown or not. |
