ABSTRACT:
An electronic circuit comprises a programmable cell that comprises a cell input, an output, a programmable component, programming means for selectively changing a state of the component, and coupling means for providing a signal path from the cell input to the output dependent on the component's state. The programmable component, e.g., a fuse, is located outside the signal path. Capacitances that limit the speed of operation in the read mode are considerably lower than in the prior art.
