ABSTRACT:
A data storage element (10) comprises a switch (11) and a ferroelectric capacitor (12). The switch (11) has a control terminal connected to a word line (13), a first current conducting terminal coupled to a bit line (16) via the ferroelectric capacitor (12), and a second current conducting terminal connected to a plate line (14). The data storage element (10) fully restores data in the ferroelectric capacitor (12) after a reading operation without consuming extra power to boost the word line (13) voltage.
