Abstract:
Methods, systems, and devices for a sensing scheme that extracts the full or nearly full remnant polarization charge difference between two logic states of a ferroelectric memory cell or cells is described. The scheme employs a charge mirror to extract the full charge difference between the two states of a selected memory cell. The charge mirror may transfer the memory cell polarization charge to an amplification capacitor. The signal on the amplification capacitor may then be compared with a reference voltage to detect the logic state of the memory cell.

Claim (Index 2):
A method of operating a memory cell, comprising:\n extracting a first charge stored in the memory cell through a charge mirror; extracting a second charge stored in an amplification capacitor through the charge mirror based at least in part on extracting the first charge stored in the memory cell, wherein the amplification capacitor is in coupled with the memory cell via the charge mirror; and comparing a voltage associated with the amplification capacitor to a reference voltage, wherein the voltage of the amplification capacitor is based at least in part on the second charge being extracted from the amplification capacitor.
