摘要： A semiconductor device includes a control signal generation circuit and an input/output control circuit. The control signal generation circuit enters a copy operation based on a combination of logic levels of first and second operation control signals and generates a transfer control signal according to a detection result of logic levels of bits included in first internal data during the copy operation. The input/output control circuit generates first data and second data by inverting or non-inverting the logic levels of the first internal data based on the transfer control signal.

摘要： An internal strobe signal generating circuit may include a data rate selection circuit, a division circuit and a strobe output circuit. The data rate selection circuit may enable a data rate selection signal according to operational information. The division circuit may generate a divided strobe signal by dividing a data strobe signal in response to the data rate selection signal. The strobe output circuit may generate, in response to the data rate selection signal, an internal strobe signal based on one of the divided strobe signal and the data strobe signal.
