Abstract
An information holding device comprises a pair of substrates having a first electrode and a second electrode oppositely formed on opposing surfaces thereof, and a dielectric material held between the pair of substrates. A capacitance of the dielectric material between the first and second electrodes is changed and a voltage varying with time is applied to the dielectric. A displacement current flowing through the dielectric is then detected.
