Abstract
A circuit and method performs a write assist for a memory cell (e.g., a static random access memory cell (SRAM)). The method includes providing a lower supply voltage signal to a voltage supply node of the memory cell using a capacitor. The lower supply voltage signal is lower in voltage level than a supply voltage signal. The method further includes lowering a common signal provided to a write driver using the capacitor.
