Common-mode comparison based fuse-readout circuit

Abstract:

Systems and methods are provided that sense a state of a fuse located in a fuse array. These methods involve a logic gate that selectively transmits outputs from respective comparators based on the combination of outputs received at the logic gate. The comparators generate outputs based on comparing a signal received indicative of the fuse state and a reference voltage. The described systems and methods reduce power consumption of a fuse sensing device since portions of the fuse sensing device are deactivated when not sensing and enable single fuse reading to occur, among other advantages.
