Abstract
A semiconductor device includes a first input/output (I/O) part buffering command/address (C/A) signals inputted through a first pad part to generate delay address signals, an internal address generator generating a plurality of internal address signals according to a level combination of the delay address signals, and a second I/O part including a plurality of fuses selected by the plurality of internal address signals in a test mode. The plurality of fuses of the second I/O part are programmed according to logic levels of data inputted to the second I/O part through a second pad part to control I/O characteristics of the second I/O part.
