Abstract
A fuse data reading circuit is configured to read fuse data in multi-reading modes. The fuse data may be stored in a fuse array that includes a plurality of fuse cells configured to store fuse data. The fuse data reading circuit may include a sensing unit configured to sense the fuse data stored in the fuse cells of the fuse array, and a controller configured to control an operation of reading the fuse data stored in the fuse cells. The controller sets different sensing conditions for sensing the fuse data according to an operation period during the fuse data reading operation to read the fuse data. Methods include operations and use of the fuse data reading circuit.
