ABSTRACT:
An apparatus for generating a DBI signal in a semiconductor integrated circuit includes a full adder that includes data input terminals and a carry input terminal, each of which receives data, performs an operation on the received data, thereby outputting a sum and a carry. A half adder includes data input terminals, each of which receives data, performs an operation on the received data, thereby outputting a sum and a carry. A DBI determining unit determines a logic value of each of the data according to the sums and the carries that are transmitted from the full adder and the half adder, thereby outputting a DBI signal.
