Abstract
A method for calibrating a data strobe (DQS) signal and associated circuit is provided. The calibrating method includes determining N buffers from a delay chain having M buffers to delay a predetermined phase during a first period; serially connecting the N buffers of the delay chain during a second period; and inputting the DQS signal to the N serially connected buffers to delay the DQS signal by the predetermined phase.
