Abstract
The fast-decay component of the retained polarization in lead zirconat e titanate ferroelectric capacitors was examined as a function of writ e/read voltage, number of cycles (fatigue), and temperature. The perce ntage of polarization loss within 1 s after the write pulse was found to be independent of the write/read voltage and only somewhat dependen t upon the number of read/write cycles and temperature. A preliminary model is presented based on depolarizing fields within the ferroelectr ic due to nonswitching layers at the top and bottom interfaces.
