ABSTRACT:
In a memory device that operates at high speed, a bit-line sense amplifier driver is provided to overdrive a sense amplifier in a refresh mode. A bit-line sense amplifier driver includes a refresh overdriving control unit that is coupled to an external power supply terminal and a sense amplifier power line signal output terminal, and driven by a refresh flag signal and a sense amplifier power line enable signal to apply an external supply voltage to the sense amplifier power line signal output terminal in a refresh mode.Therefore, it is possible to prevent a driving voltage from serving as noise, which hinders the high speed operation of the memory device.
