A ferroelectric memory includes a memory cell array having a plurality of
memory cells with ferroelectric capacitors arranged therein, a plurality
of word lines, a plurality of plate lines, and a plurality of plate line
selection circuits. An L-th plate line selection circuit among the
plurality of plate line selection circuits includes a first transistor
that is provided between an L-th plate line and a supply node for
supplying an I-th plate line selection signal and turns on when a K-th
word line is set to a selection voltage to thereby supply the I-th plate
line selection signal to the L-th plate line, and a second transistor
that is provided between the L-th plate line and a first power supply and
turns on when the K-th word line is set to a non-selection voltage to
thereby set the L-th plate line to a voltage level of the first power
supply.
