Abstract
A semiconductor memory device for compensating latency by stacking reference data. The semiconductor memory device compensates the latency and test errors between two signals by detecting the latency of the two signals and stacking the reference data without using an extra signal. Accordingly, a system can be simplified and power consumption can be reduced when testing the semiconductor memory device, since the extra circuit is unnecessary to synchronize a data sync signal with output data.
