Abstract

A semiconductor integrated circuit includes a self-test circuit, wherein, when a operation mode of the self-test circuit has been switched from a low-speed operation mode to a high-speed operation mode, processing is performed in the high-speed operation mode during a given time period, and the processing result is invalidated based on a control signal.
