Strobe signal generation circuit and semiconductor apparatus including the same

A strobe signal generation circuit comprising:

• a trigger circuit configured to generate a first pull-up signal, a second pull-up signal, a first pull-down signal, and a second pull-down signal based on differential clock signals and an on-die termination signal;
• a first main driver configured to generate a differential data strobe signal in response to receiving the first pull-up signal and the first pull-down signal;
• and
• a second main driver configured to generate an other differential data strobe signal in response to receiving the second pull-up signal and the second pull-down signal through opposite terminals than the first main driver received the first pull-up signal and the first pull-down signal.

A semiconductor apparatus comprising:

• a core block including a memory cell array;
• a pad array including pads for input/output of data and pads for outputting differential data strobe signals for notifying a receiving side of output data;
• a data processing circuit configured to, in a read operation, serialize and drive parallel data outputted from the core block, by using a clock signal, and output resultant data through the pads for input/output of data to an exterior of the semiconductor apparatus;
• and
• a strobe signal generation circuit configured to generate the differential data strobe signals according to the clock signal,
• the strobe signal generation circuit comprising
• a trigger circuit configured to generate at least one pull-up signal and at least one pull-down signal according to the clock signal;
• a first main driver configured to generate a differential data strobe signal in response to receiving a pull-up signal from among the at least one pull-up signal and a pull-down signal from among the at least one pull-down signal;
• and
• a second main driver configured to generate an other differential data strobe signal in response to receiving an other pull-up signal from among the at least one pull-up signal and an other pull-down signal from among the at least one pull-down signal through opposite terminals than the first main driver received the pull-up signal and the pull-down signal.
