Title: FUSE STATE SENSING CIRCUITS, DEVICES AND METHODS
Abstract:
Fuse state sensing circuits, devices and methods. In some embodiments, a fuse state sensing circuit can include an enable block configured to enable a flow of a fuse current resulting from a supply voltage to a fuse element upon receipt of an enable signal substantially at the same time as when the supply voltage is applied. The fuse state sensing circuit can further include a current control block tailored to control an amount of the fuse current. The fuse state sensing circuit can further include a decision block implemented to generate an output representative of a state of the fuse element based on the fuse current, with the output being generated during a ramp-up portion of the application of the supply voltage.
