An apparatus for measuring data setup/hold time is capable of effectively measuring a setup/hold time of data, and includes a data generating unit for delaying an external clock signal according to counting signals and generating an internal clock signal and data signals from the delayed external clock signal in response to test signals, a flag signal generating unit for generating flag signals according to the internal clock signal and the data signals, and a counter for producing the counting signals in response to the flag signals. |
