Abstract:
Methods for sensing ferroelectric memory devices and apparatuses using the same have been disclosed. One such apparatus includes a ferroelectric memory cell coupled to a data line, a reference capacitance, and a common node coupled between the data line and the reference capacitance. A current mirror circuit is coupled to the data line and the reference capacitance. During a sense operation, the common node is configured to be at a fixed voltage and the current mirror circuit is configured to mirror displacement current from the reference capacitance to the ferroelectric memory cell.
