The invention provides a ferroelectric storage apparatus which can reduce
or prevent disturbance, a driving method therefor, and a driving circuit
therefor. In the ferroelectric storage apparatus, an operation step of
applying one of data reading, data re-writing, and data writing to at
least one selected cell among a plurality of ferroelectric memory cells
formed at the intersections of a plurality of word lines and a plurality
of bit lines is repeatedly performed. A disturbance prevention step of
applying a voltage to each of the plurality of ferroelectric memory cells
in an electric-field direction in which the stored data of each
ferroelectric memory cell is not inverted is performed after the operation
step is executed at least once. With this, a voltage is applied to
not-selected cells at a certain frequency in an electric-field direction
in which the stored data of the not-selected cells is not inverted, and
data deterioration is reduced or suppressed.
