1. An integrated circuit, comprising:

  • a first charge pump including;

    a plurality of serially arranged charge pump stages of the first charge pump arranged to pump a first voltage level from a first stage to a last stage of the first charge pump; and

    inter-stage nodes between adjacent stages of the plurality of serially arranged charge pump stages; and

    a second charge pump coupled to one or more of the inter-stage nodes of the first charge pump, the second charge pump arranged to pump one or more voltage levels of the one or more of the inter-stage nodes of the first charge pump, the second charge pump including;

    a plurality of serially arranged charge pump stages of the second charge pump arranged to pump a second voltage level from a first stage to a last stage of the second charge pump,wherein an input clock signal received by the integrated circuit (i) determines a pumping frequency of the first charge pump, and (ii) clocks data including memory commands and memory addresses received by the integrated circuit.
