Abstract
A system-on-chip (SoC) includes a fuse circuit and decoding circuitry. The fuse circuit includes functional fuses, control fuses utilized as the functional fuses, and fuses configured to store override data that indicates an association between the functional fuses and the control fuses utilized as the functional fuses. The decoding circuitry is configured to output configuration data associated with a configuration of the fuse circuit based on the override data and an initial configuration of the fuse circuit. In such a scenario, functional operations of the SoC are executed based on the configuration data. Alternatively, the decoding circuitry is configured to output a set of functional data based on the override data and various functional data stored in the functional fuses and the control fuses utilized as the functional fuses. In such a scenario, the functional operations are executed based on the outputted set of functional data.
