AN ANTI-FUSE CIRCUIT FOR THROUGHPUT IMPROVEMENT AND A CIRCUIT FOR CHECKING SHORT OF THE ANTI-FUSE

摘要

An anti-fuse circuit for throughput improvement and a circuit for checking short of an anti-fuse are provided to increase the number of anti-fuses capable of being short within a constant time through a program corresponding to each equipment, by preventing a current flowing in the anti-fuse after the anti-fuse is blown. At least one anti-fuse(220) becomes short-circuit according to program operation, and has a variable resistance value. At least one comparison resistor(230) becomes a reference to prevent a current flowing in the anti-fuse. At least one current blocking part(240) determines to prevent the current flowing in the anti-fuse by comparing the resistance value of the anti-fuse with the comparison resistor during program operation.
