Abstract
After data readout, in equalizing a complementary pair of bit lines one of which has been overdriven with an overdrive voltage, excessive charges on the overdriven bit line are discharged by a discharge circuit. By adjusting the discharge period of the discharge circuit, the potential to which the bit lines are equalized is adjusted.
