Abstract
Voltage distribution between ferroelectric capacitor/capacitors and normal capacitor in ferroelectric devices is difficult to calculate or simulate due to the complicated electrical properties of the ferroelectric capacitor. This paper presents a mathematical method combined with graphic solution to analyze the voltage distribution. Analysis of voltage distribution of different structures (1FC/1NC, 2FC, 2FC/1NC) or operation patterns is summarized. The dependence of the medial value and difference of bitline voltages between “0” and “1” state after the driving pulse of plateline on the value of Cb/Cfm has been analyzed.
