Abstract
An integrated circuit having a predetermined function includes a signal generating circuit for generating a signal for performing a reliability test predetermined in the integrated circuit, a detecting circuit for outputting a signal which indicates a detection at a time when a rise of a supply voltage to the integrated circuit is detected, and a control circuit for controlling the integrated circuit so that a predetermined reliability test of the integrated circuit is performed by using the signal output from the signal generating circuit in case that a predetermined selection signal is applied to an input terminal of the control circuit in response to the signal output from the detecting circuit at a time of a rise of the supply voltage.
