1. An apparatus, comprising:

  • a first node to receive a signal that switches between first and second voltages;

    a voltage level shifter to assert one of the second voltage and a third voltage at a second node based on a voltage at the first node, wherein the second voltage is greater than the first voltage, and wherein the third voltage is greater than the second voltage; and

    a charge pump assist circuit to assert a same one of the second and third voltages at the second node as the voltage level shifter, based on the voltage at the first node.
