Patent ID: 6838926

Claim:
A fuse circuit for a semiconductor integrated circuit, comprising: a plurality of fuses; and a like plurality of transmission circuits, each of the plurality of fuses being coupled to only one corresponding transmission circuit of the plurality of transmission circuits; each transmission circuit having a single input at an input node and a single output at an output node for transferring signals from the input node to the output node in response to a status of the corresponding fuse, the input and output nodes of respective transmission circuits being coupled such that the transmission circuits are arranged in series, such that an input signal applied to the input node of a first transmission circuit in the series is transferred to the output node of a last transmission circuit in the series when all of the transmission circuits in the series are in an active state and such that the input signal is not transferred from the input node of the first transmission circuit to the output node of the last transmission circuit in the series when at least one of the transmission circuits in the series is in an inactive state.
