Abstract :
Summary form only given. This paper describes ferroelectric memories (FRAMs) embedded in microcontrollers. The first device to be commercialized by Panasonic/Symetrix is an 8-bit RISC processor with 64 kbits of FRAM, using the layered Perovskite Y-1 material. This FRAM is implemented using double level metal. An RF-coupled smart card uses this device on a single chip realization of a transponder, power circuit, microcontroller and memory. Further developments are also discussed for higher density devices and controllers of up to 32-bit words
