Patent attributes
Various systems and methods for device configuration are disclosed herein. For example, some embodiments of the present invention provide semiconductor devices that include a fuse blow circuit. The fuse blow circuit provides two fuse blow outputs. Assertion of one of the fuse blow outputs causes one electronic fuse to blow, and assertion of the other fuse blow output causes another electronic fuse to blow. One of the electronic fuses represents a configuration bit while the other electronic fuse represents an inversion status bit indicating an inversion to be applied to the configuration bit. Both the configuration bit and the inversion status bit are applied to an inverter which operates to invert the configuration bit based at least in part on the inversion status bit.
