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 .
