Methods, systems, and devices for operating a ferroelectric memory cell or cells are described. The magnitude of a voltage applied across a ferroelectric capacitor may be dynamically increased during a write operation. A memory cell may be selected for a write operation, and a voltage may be applied to a digit line corresponding to the memory cell during the write operation. An additional charge may be transferred to the digit line—e.g., from an energy storage component, such as a capacitor, that is in electronic communication with the digit line. In turn, the voltage across the ferroelectric capacitor of the memory cell may be increased.
