ABSTRACT:
An apparatus for generating a DBI signal in a semiconductor memory apparatus includes a data switching detection unit that detects whether or not previous data is consistent with current data and outputs a detection signal according to a detection result, and a DBI detection unit that outputs a DBI signal according to a difference in charge sharing level using the detection signal. Therefore, it is possible to minimize current consumption. Further, since there is no effect due to resistance skew of a transistor, an error in DBI signal generation and an error in data transfer accordingly can be prevented. Therefore, it is possible to improve the reliability of a system to which a semiconductor memory apparatus is applied.
