Abstract
A ferroelectric-capacitor-gate Si MOSFET which consists of an SiO2/Si MOSFET and a ferroelectric capacitor has been demonstrated. It is show n that memory functions can be obtained by connecting the ferroelectri c capacitor with the gate of MOSFETs. The operation of such devices is similar to that of metal-ferroelectric-semiconductor (MFS) FETs. The large memory window or threshold voltage shift can be obtained with a ferroelectric capacitor which has a large coercive voltage. The memory effect of the device has been demonstrated by showing the drain curre nt change by a previously applied ''write'' pulse at a fixed gate volt age of 0V.
