Abstract
A fuse circuit includes electrical fuse elements which are commonly connected at one-side ends, a voltage generating section and a readout section. The voltage generating section is configured to selectively apply program voltage for destroying the electrical fuse element and read voltage for reading out the destructive/nondestructive states of the electrical fuse elements to a common connection node of the one-side ends of the electrical fuse elements. The readout section is configured to read out the destructive/nondestructive states of the electrical fuse elements from the other ends of the electrical fuse elements when the read voltage is applied to the common connection node from the voltage generating section.
