An integrated circuit that is capable of being burn-in tested with an AC stress and a testing method using the same are provided. The integrated circuit includes an address transforming means and a data generating means. The address transforming means transforms the addresses of the memory device selected and generates an address signal responsive to a clock signal. The data generating means generates a data signal that alternates between a first state and a second state responsive to the clock signal and provides the data signal to the selected memory device. The integrated circuit includes a switch for coupling the test supply line to the normal supply line during testing and intercepting the test supply line from the normal supply line during normal operations responsive to a control signal. The integrated circuit of the present invention allows a wafer burn-in test by sequentially and repeatedly applying the AC stress to all the memory devices.
