Abstract:
1. A semiconductor memory device, comprising: a first strobe signal generation unit configured to generate a first rising strobe signal in response to a rising DLL clock signal; a second strobe signal generation unit configured to generate a second rising strobe signal in response to a falling DLL clock signal, the second rising strobe signal having an opposite phase to the first rising strobe signal and being activated at the same timing as the first rising strobe signal; a third strobe signal generation unit configured to generate a first falling strobe signal in response to the falling DLL clock signal; and a fourth strobe signal generation unit configured to generate a second falling strobe signal in response to the rising DLL clock signal, the second falling strobe signal having an opposite phase to the first falling strobe signal and being activated at the same timing as the first falling strobe signal.
