The programming fuse circuit is comprised of a fuse for programming 103, which is connected between the first voltage supplying circuit 101 and the second voltage supplying circuit 102, and also which is cut off as necessary, and a hold/driver circuit 106, which is connected to a contact 100. Wherein, the first voltage supplying circuit 101 provides a first voltage for the contact 100 in conformity with the first initializing signal, which is generated during the time for setting the device operating mode. The second voltage supplying circuit 102 provides a second voltage for the contact 100 in conformity with the second initializing signal 105, which is generated also during the time for setting the device operating mode. The hold/driver circuit 106 holds either the first voltage supplied or the second voltage supplied, and outputs it.
