Abstract
Methods and apparatus to control voltage output of a write assist circuit are disclosed. An example method includes regulating pull down voltage from a write assist circuit having a write assist capacitor coupled to a discharge node coupled to a bit line. The write assist circuit further includes a transistor to receive an enable signal to couple the bit line to a low voltage rail. A voltage source is provided to charge the capacitor. The voltage produced by the voltage source is limited to limit the pull down voltage at the discharge node from the write assist capacitor.
