ABSTRACT:
A ferroelectric memory device that is equipped with a cell array provided with a plurality of memory cells each having a first ferroelectric capacitor and a second ferroelectric capacitor that are connected to each other in series, a memory cell selection section that selects a specified one of the plurality of memory cells, a potential difference generation section that gives a potential difference across one end and another end of the selected memory cell, and a judging section that judges memory data stored in the memory cell based on a potential at a connection node between the first ferroelectric capacitor and the second ferroelectric capacitor when the potential difference is given to the memory cell.
