Detailed equivalent circuit models of ferroelectric and high-permittiv
ity dielectric capacitors are required for the development of FeRAM an
d ultra-dense DRAM devices. This review comprises the frequency depend
ence of C-V and P-V characteristics, grain size effects, electrode int
erface effects, as well as reversible and irreversible contributions t
o the ferroelectric polarization and discusses their impact on the equ
ivalent circuit modeling.
