Methods, systems, and devices for operating a ferroelectric memory cell or cells are described. A ferroelectric capacitor of a memory cell may be in electronic communication with a sense capacitor through a digit line. The digit line may be virtually grounded during memory cell sensing, limiting or avoiding voltage drop across the digit line, and allowing all or substantially all of the stored charge of the ferroelectric capacitor to be extracted and transferred to the sense capacitor. Virtually grounding the digit line may be achieved by activating a switching component (e.g., a p-type field-effect transistor) that is electronic communication with the digit line. The charge of the ferroelectric capacitor may be transferred through the switching component. 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.
