Abstract
Disclosed herein is a semiconductor device including a non-volatile memory unit. The non-volatile memory unit has a subject current path disposed in a semiconductor integrated circuit and a fuse element inserted in series on the subject current path, and changes output data according to a voltage between both ends of the fuse element when supply of a subject current to the subject current path is intended. A current supply part that switches the subject current between a plurality of stages is disposed in the non-volatile memory unit.
