    摘要: A semiconductor integrated circuit device includes a first memory circuit which stores normal data, a second memory circuit which stores determination information used to determine whether a value of the normal data is changed or not, and a determination circuit which determines whether a value of the normal data is changed or not based on the determination information. The capacitance of a data storage node of the second memory circuit is larger than that of a data storage node of the first memory circuit.
