Abstract

The bit size dependence on the pulse width and pulse voltage in ferroelectric memory devices was studied by applying pulses through the atomic force microscopy (ATM). The electrical field distribution inside the Pb(Zr0.4Ti0.6)O3 (PZT) films was calculated to predict the bit size variation with the pulse width and the pulse voltage. The linear dependence of the bit size on the logarithmic value of the pulse width was also investigated. It was found that the minimum stable bit size exists which equals the film thickness.
