Abstract
A semiconductor memory device can include a first driver configured to generate a pair of first sense amplifier driving signals having an activation period at a predetermined level during command execution; and a second driver that can be configured to generate a pair of second sense amplifier driving signals for increasing a driving strength of a pair of sense amplifiers when logic values of a pair of bit lines are constant during the command execution and decreasing the driving strength of the pair of sense amplifiers when the logic values of the pair of bit lines change.
