ABSTRACT:
A timing signal generating circuit has a plurality of timing signal generating units disposed in series, each including three or more pieces of timing signal generating elements connected in parallel, and a connecting unit disposed in between the plurality of timing signal generating units. The connecting unit includes an arithmetic circuit which outputs relatively majority signal among outputs of the timing signal generating elements.
In this circuit, if some of the timing signal generating elements output defective signals, normal signal is picked-up and output through majority operation of the arithmetic circuit without repairing.
