Abstract
Disclosed is a semiconductor memory device including: a sense amplifier capable of sensing and amplifying data loaded on a data-line pair based on a pull-up driving voltage and a pull-down driving voltage; a pull-up driving unit capable of supplying a first voltage as the pull-up driving voltage for first and third active sections of an active mode, and supplying a second voltage having a voltage level lower than the first voltage as the pull-up driving voltage for a second active section of the active mode, between the first and third active sections of the active mode; and a pull-down driving unit capable of supplying a third voltage as the pull-down driving voltage for the first to third active sections of the active mode and for an initial section of a precharge mode after the active mode.
