Abstract: A burn-in method for synchronous memory that utilizes synchronous signals for the burn-in operation. Using synchronous clock pulse signals for burning in the synchronous memory is able to exercise the burst output mode and the pipeline function, and hence the optimum burn-in results can be obtained. Furthermore, synchronous burn-in not only can increase the processing speed up to twice the conventional asynchronous burn-in method, but can simulate of the actual working environment of the synchronous memory as well. Moreover, an asynchronous burn-in method can be selected whenever required without any penalty.
