Abstract
A clock locking method of a memory device, may include performing an initial locking operation in a delay locked loop circuit before an internal voltage is stabilized, monitoring clock skew between a reference clock and a feedback clock using a window detection circuit after the internal voltage is stabilized, and performing a re-locking operation in the delay locked loop circuit using a dynamic delay control corresponding to the clock skew.
