Ferroelectric memory applications

Recent applications of ferroelectric thin-film memory devices are discussed. A brief description of processing alternatives and device physics is followed by some prototype architecture for Si MOSFET and GaAs JFET structures. Specific applications include radiation-hardened satellite memories, automobile nonvolatile dashboard memories, electronic camera memories, and smart credit cards and inventory devices. Shadow-RAMs, SRAMs, and DRAMs are described. Replacement of NMOS, core, EEPROM (electrically erasable programmable read-only memory), magnetic bubble memory, plated wire, and CMOS with battery backup seems possible within a few years.<
