A method and apparatus for measuring a delay time is provided. First, a plurality of first/second phase signals, a first/second standard signal, and an inverse signal of the second standard signal are generated. The inverse signal of the second standard signal is applied to a second conductive line close to at least an adjacent conductive line. The first/second standard signal is applied to the first/second conductive line to obtain a first/second transmission signal. Then, the first/second transmission signal is sequentially sampled by the first/second phase signals to sequentially obtain a plurality of first/second sampling results. The first/second sampling results are sequentially identified by a first/second identifying level to obtain a first/second identification result. Accordingly, the delay time between the first and the second transmission signal may be obtained by comparing the different the second and the first identification result.
