Abstract
In a ferroelectric memory, a plate line and a complementary bit line are electrically connected with each other by a MOS transistor turned on, so that a voltage of the complementary bit line amplified by a sense amplifier is transferred to the plate line. An electric current for driving the plate line flows only when the voltage of the complementary bit line is different from that of the plate line. Because the sense amplifier can drive the plate line, it is unnecessary to provide the ferroelectric memory with a plate line-driving circuit.
