Abstract
An operating method for a semiconductor memory device includes: generating a whole-domain-crossing-unit reset signal based on a domain-crossing-unit reset signal input to a whole-domain-crossing-unit-reset-signal generator; and resetting a counter synchronized to a data clock of a domain-crossing unit based on the whole-domain-crossing-unit reset signal during a data clock preparation section in which the data clock does not toggle.
