A ferroelectric memory device includes: a plurality of bit lines; a plurality of memory cells connected to each of the plurality of bit lines, and each storing "0" data with a smaller amount of readout charge or "1" data with a greater amount of readout charge according to a polarization state; a plurality of data lines; a plurality of charge transfer circuits that connect the plurality of bit lines to the plurality of data lines, respectively, based on a potential on each of the bit lines; a capacitor connected to each of the plurality of data lines for storing negative charge; a positive charge canceling circuit that pulls out positive charge corresponding to the amount of "0" data readout charge from each of the plurality of bit lines; and a sense amplifier that judges data read out from the memory cells.
