Abstract
The present invention provides a semiconductor memory device adjusting a bit line over driving period according to a power supply voltage level. A semiconductor memory device for stabilizing a bit line sense amplifier (hereinafter, referred as BLSA) includes the BLSA operated by a sense amplifier driving voltage; and a controller for comparing a feedbacked sense amplifier driving voltage with a reference voltage to thereby control the sense amplifier driving voltage to the BLSA.
