  • Patent number: 10600467
    Abstract: Methods, systems, and devices for operating a ferroelectric memory cell or cells are described. Offsets in the threshold voltage of switching components (e.g., transistors) connected to digit lines may be compensated by using various operating techniques or additional circuit components, or both. For example, a switching component connected to a digit line may also be connected to an offset capacitor selected to compensate for a threshold voltage offset. The offset capacitor may be discharged in conjunction with a read operation, resulting in a threshold voltage applied to the switching component. This may enable all or substantially all of the stored charge of the ferroelectric memory cell to be extracted and transferred to a sense capacitor through the transistor. A sense amplifier may compare the voltage of the sense capacitor to a reference voltage in order to determine the stored logic state of the memory cell.
