A semiconductor memory device having a driver configured to sequentially perform over-driving and normal driving operations is presented. The semiconductor memory device includes a driver that outputs a drive signal, that over-drives the drive signal with an over-drive voltage having a voltage level higher than a normal drive voltage, and then subsequently normally drives the drive signal with the normal drive voltage. The semiconductor memory device also includes a drive voltage adjuster that detects a level of the over-drive voltage and compensates for a change in the voltage level of the normal drive voltage in response to the detected level of the over-drive voltage.
