Abstract:
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.
