ABSTRACT:
A comparator circuit for comparing outputs of an on-chip redundant system is mounted on a second semiconductor chip that is separate from the on-chip redundant system. The second semiconductor chip which preferably contains a power source circuit for supplying power to the on-chip redundant system, a driver circuit for driving an output circuit, and the like are mounted. With this configuration, the influence of a failure occurring in the on-chip redundancy system can be prevented from being exerted on the comparator measure.
