| 摘要 |
A fuse state detection circuit ( 300 ) has a reference circuit part ( 302, 302 ') and a fuse detection circuit part ( 308, 308 '), the reference circuit part ( 302, 302 ') having a fuse ( 304, 304 ') identical to a fuse ( 306, 306 ') under detection. A reference voltage is between a voltage of a blown fuse ( 306, 306 ') under detection and a voltage of an un-blown fuse ( 306, 306 ') under detection, thus distinguishing a blown state of the fuse ( 306, 306 ') under detection from an un-blown state of the fuse ( 306, 306 ') under detection.
