Abstract

An unclocked electrically programmable fuse (eFUSE) system includes at least two resistive voltage dividers, one voltage divider including an eFUSE, and a differential amplifier. An output node of at least one of the voltage dividers includes an eFUSE that changes an output voltage based on a state of the eFUSE, and the differential amplifier changes the output voltage into a digital output with no clocking capabilities.
