Abstract

To detect deterioration of a correction memory, provided is a semiconductor device including the correction memory that stores therein correction data for correcting a correction target; a correcting section that corrects a detection value of a sensor element, using correction data read from the correction memory; a diagnosing section that diagnoses the correction memory, using the correction data read from the correction memory; and a control section that controls reading conditions used when reading the correction data from the correction memory, wherein the control section causes a first reading condition, used when reading the correction data for correcting a correction target, to differ from a second reading condition, which is used when reading the correction data for the diagnosis.
