PROBLEM TO BE SOLVED: To provide an apparatus and a method for generating a DBI signal in a semiconductor integrated circuit, capable of realizing high integration by increasing an area margin. SOLUTION: The apparatus includes: full adders 10 and 20 that includes data input terminals D1 and D2 and a carry terminal CI, each of which receives data, performs an operation on the received data, thereby outputting a sum and a carry; a half adder 30 that includes data includes data input terminals D1 and D2, each of which receives data, performs an operation on the received data, thereby outputting a sum and a carry; and a DBI discrimination unit that discriminates a logic value of each of the data from the sums and the carries transmitted from the full adders 10 and 20 and the half adder 30, and generates a DBI signal.
