Abstract
A clock pattern generating method of a semiconductor memory device is provided. The method includes generating the same clock pattern through a plurality of detection clock output pins when an output selection control signal is in a first state and generating clock patterns different from each other through the plurality of detection clock output pins when the output selection control signal is in a second state different from the first state.
