摘要

LATELY, the ferroelectric random access memories (FRAM) have become one of the most attractive subjects in solid devices due to faster access time as dynamic RAM, the non-volatility as erasable programmable read-only memory, radiation-hardness and lower power requirements. Perovskite ferroelectrics such as Pb(ZrTi)O_3 (PZT) are the most popular ferroelectric thin film materials. However, commercial usage has been hindered by serious degradation problems of PZT materials, such as fatigue. In 1995, C.A-Paz de Araujo et al. reported that layered perovskite-like ferroelectrics had fatigue-free characteristics. Capacitors made from these materials did not show significant fatigue after 10~(12) switching cycles and exhibited good retention characteristics and low leakage currents.
