Abstract
A pair of write driver inverters are arranged in series to drive a bit line responsive to a data bit input signal. A first boost capacitor provides a negative boost to a first ground node for a first one of the write driver inverters during the write assist period. A second boost capacitor provides a negative boost to a second ground node for a second one of the write driver inverters during the write assist period.
