Abstract
A semiconductor integrated circuit device includes an operating mode setting circuit for determining an operating mode. Operating mode setting circuit includes an operating mode control circuit and an operating mode alteration circuit. Operating mode control circuit generates an operating mode setting signal depending on wire bonding provided to external input pads. Operating mode alteration circuit includes fuse input pads, electric fuses, and an operating mode inverting circuit. Operating mode inverting circuit inverts an operating mode setting signal once determined by blowing each of electric fuses.
