Abstract
A semiconductor memory device includes an active state detector suitable for detecting whether or not a predetermined time passes after a moment when a normal active command or an additional active pulse is activated in an active state detection mode, and generating an additional precharge pulse based on a detection result, a column controller suitable for generating the additional active pulse based on the additional precharge pulse, a column address, and an external column command in the active state detection mode, and a core region suitable for being activated based on the normal active command or an additional active command corresponding to the additional active pulse, and being precharged based on an additional precharge command corresponding to the additional precharge pulse or a normal precharge command.
