ABSTRACT:
A fuse programming circuit having reduced energy consumption is coupled between a first potential and a second potential for providing a programmable voltage level at an output node. The electrical circuit has a fuse element having a first terminal coupled to the output node and a second terminal coupled to the first potential. The electrical circuit also has means for providing a path for passing electrical charge between the second potential and the output node, which the path between the second potential and the output node has substantially infinite resistance when the electrical charge is being transferred.
