A configurable electronic circuit having configuration nodes is provided. Each of the configuration nodes is coupled to corresponding first circuitry that is non-modifiable during configuration and second circuitry that is modifiable during the configuration. The non-modifiable first circuitry selectively imposes one of at least a first potential and a second potential on the configuration node prior to configuration, and the modifiable second circuitry allows modification of the potential imposed on the configuration node by the non-modifiable first circuitry. In a preferred embodiment, the modifiable second circuitry includes at least one fuse that is in an intact state before configuration and that can be changed to a destroyed state after configuration. This enables a reduction in the number of fuses that have to be destroyed during the configuration of the circuit. Also provided is an information processing system that includes at least one configurable electronic circuit having configuration nodes.
