FUSE DATA READING CIRCUIT WITH MULTIPLE READING MODES

摘要

PURPOSE: A fuse data reading circuit with multiple reading modes minimizes reading errors of fuse data in a section that the reading operation environment is unstable by reading the fuse data in multiple reading modes. CONSTITUTION: A fuse array (140) includes multiple fuse cells storing fuse data. A sensing unit (150) senses the fuse data stored in the fuse cells of the fuse array. A controller (110) controls the operation of reading the fuse data stored in the fuse cells. The controller differently sets sensing conditions to sense the fuse data according to operation sections in the fuse data reading operation and reads the fuse data.
