Patent ID: 7012828

Claim:
A data control device using a nonvolatile ferroelectric memory, comprising: a radio data processing unit for converting radio data having different types into digital/analog signals, and for transmitting/receiving the converted signals wirelessly; and a FeRAM memory unit for encoding the radio data having different types and storing the encoded data in unit cells of a nonvolatile ferroelectric memory, respectively, for comparing a plurality of different cell data sensing voltages sensed in the nonvolatile ferroelectric memory with a plurality of previously set reference voltages, and for converting the comparison results into digital signals to output the converted signals into the radio data processor; wherein the FeRAM memory unit includes a sense amplifier array unit for comparing the plurality of different cell data sensing voltages in a read mode with a plurality of previously set reference voltages, and for outputting the comparison results into the radio data processing unit.
