Abstract
A semiconductor integrated circuit driven by an external power, comprises a change unit whose state changes with lapse of time without the external power, an output unit configured to output a signal in response to an instruction issued when the external power is supplied, the signal indicating a change of the state of the change unit, and an execution unit configured to execute a process in response to the signal. Therefore, the circuit is capable of utilizing time-point/time-period information even if they are not supplied with power.
