A testing apparatus and a method for testing a semiconductor devices array, which includes a plurality of rows and a plurality of columns, are provided. The testing apparatus includes a first testing circuit and a second testing circuit. The first testing circuit connects and transmits a clock signal, an input command signal and a data signal to at least one of the rows of the semiconductor devices array. The second testing circuit connects and transmits a selecting signal to at least one of the columns of the semiconductor devices array. Between two devices in a row, a difference in arrival times of the clock signal, a difference in arrival times of the input command signal, and a difference in arrival times of the data signal are equal. |
