  • Publication number: 20130021894
    Abstract: Apparatus and method for transducing data from a ferroelectric data storage medium using high frequency read modulation. In accordance with some embodiments, a ferroelectric data transducer has a write electrode, a doped semiconductor layer with a source, a drain and a channel therebetween, and an insulating layer disposed between the channel and the write electrode. A write circuit applies a time varying write signal at a first frequency to the write electrode to write a corresponding sequence of data bits to an adjacent ferroelectric data storage medium. A read circuit reads the sequence of data bits from the data storage medium by applying a time varying read signal at a higher, second frequency to the write electrode and detecting changes in electrical resistance of the channel.
