<p>The data storage element (10) has an FET switch (11) and a ferroelectric capacitor (12) storage device with polarising retention. The switch has a gate (14) for receiving control signals, and a first conducting electrode coupled to the capacitor (12) for receiving restoration signals. A second electrode is connected for transmitting data. The switch can be put in a non-conducting condition and a first restoration signal can be applied via the capacitor with polarising retention. A charging voltage can be applied to a second electrode of the switch via a bit line capacitor (17). The switch can be set to a conductive state by application of a data value voltage to the second electrode in response to a voltage at the second electrode to read data from the data storage element. A second restoration signal may be applied to the first electrode, via the capacitor with polarising retention, and the switch may be placed in the non-conductive state to restore data in the data storage element.</p> |
