ABSTRACT:
A semiconductor device has change-over circuits respectively connected between data buses and a plurality of data pins, and one of the change-over circuits changes a signal path between a defective signal line to associated data pin to another signal path between a non-defective signal line the associated data pin so as to allow a common test program sequence to check the semiconductor device whether to be an excellent product or a partially defective product.
