Abstract
A fuse trimming circuit includes trimming pads, a fuse resistance, an input circuit and current limit units. The fuse resistance is configured to be connected to the trimming pads and blown out by a trimming current which flows through the trimming pads. The input circuit is configured to output one of a first potential and a second potential based on whether or not the fuse resistance is blown out. The current limit units are configured to be provided on paths from one of the trimming pads through the fuse resistance to at least one of a first power line feeding the first potential and a second power line feeding said second potential, and paths from another of the trimming pads through the fuse resistance to said at least one of the first power line and the second power line.
