Abstract
A write driver is provided that includes a first write driver inverter that inverts a data signal to drive a gate of a second write driver transistor. The write driver transistor has a terminal coupled to a bit line and another terminal coupled to a boost capacitor. A ground for the first write driver inverter floats during a write assist period to choke off leakage of boost charge from the boost capacitor through the write driver transistor.
