Abstract
A ferroelectric memory device that has a first bit line and a first plate line includes a first ferroelectric capacitor group having a plurality of ferroelectric capacitors coupled in series and in a ring shape. A switching means switches whether a ferroelectric capacitor out of the first ferroelectric capacitor group is electrically coupled to the first bit line and the first plate line.
