ABSTRACT:
A semiconductor memory device is for randomly reading and writing data. Only a second bit line pair selected by a string selecting signal is amplified by a main amplifier. The number of the upper bit line pairs to be charged and discharged from the Vcc level or Vss level is reduced to thereby reduce the consumption current of the device.
