SAFE RESET CONFIGURATION OF FUSES AND FLOPS

摘要

Methods, apparatus, and fabrication techniques relating to improved propagation of fuse data through an integrated circuit device during scan shift reset. In some embodiments, the methods comprise loading a first value of at least one fuse bit to an integrated circuit device, during a time period when a clock signal having a first frequency is provided to at least one component of the integrated circuit device; disabling a scan shift after the loading of the first value; inactivating the clock signal after the loading of the first value; propagating the first value of the at least one fuse bit to the at least one component of the integrated circuit device; and reactivating the clock signal after the propagation of the first value.
