Classification: CPC H | IPC H

Claim 15:
16. A semiconductor device, comprising:
a first seal-ring surrounding a circuit region;
a crack detection ring surrounding the first seal-ring;
a second seal-ring surrounding the first seal-ring and the crack detection ring; and
a plurality of controllers and a plurality of operators disposed inside the circuit region and electrically connected to the crack detection ring,
wherein the plurality of controllers and the plurality of operators are alternately disposed to be commonly connected to the same crack detection ring, and
wherein the plurality of controllers provides a current or a voltage to the crack detection ring and the plurality of operators includes a comparator that compares the current or the voltage, which passed through the crack detection ring, with a reference current or a reference voltage, respectively.
