User-initiatable method for detecting re-grown fuses within a microprocessor |
摘要 |
A microprocessor includes a first plurality of fuses, selectively blown with a predetermined value for provision to circuits of the microprocessor to control operation of the microprocessor. The microprocessor also includes a second plurality of fuses, selectively blown with error detection information used to detect an error in the first plurality of fuses such that a blown fuse of the microprocessor returned a non-blown binary value. In response to a user program instruction, the microprocessor is configured to determine whether there is an error in the first plurality of fuses such that a blown fuse returned a non-blown binary value using the error detection information from the second plurality of fuses. |
