Abstract
Correction of duty cycle distortion of DQ and DQS signals between a memory controller and a memory is corrected by determining a duty cycle correction factor. The duty cycle distortion is corrected by applying the duty cycle correction factor to the plurality of differential DQS signals. The duty cycle distortion is corrected across a plurality of differential DQS signals between the memory controller and the bursting memory.
