摘要：
A method of determining timing skew between data outputs of a memory device can include writing a predetermined data pattern to a memory device at a first operational frequency that is less than a normal operational frequency used to write non-predetermined data to the memory device. The memory device is read to output the predetermined data pattern therefrom at a second operational frequency that is greater than the first operational frequency and about equal to a normal operational frequency used to read non-predetermined data from the memory device. Timing skew is determined between outputs from the memory device based on the actual time when the predetermined data is provided from the memory device.
