<p>PURPOSE: An anti-fuse circuit and a fuse rupturing method thereof are provided to improve the reliability of an operation by performing normal fuse rupturing through an additional rupturing operation even in case that fuse rupturing fails. CONSTITUTION: A control block (210) generates a first control signal and a second control signal in response to a first test signal and a second test signal. A fuse set block (220) performs a first fuse rupturing operation in response to the first control signal and a second fuse rupturing operation in response to the second control signal and activates a fuse signal when one of the first fuse rupturing operation and the second fuse rupturing operation succeeds.
