1. An implantable stimulator device comprising a plurality of first electrodes and a plurality of second electrodes configured to provide stimulation to a patient'"'"'s tissue, comprising:

  • a first integrated circuit comprising a first stimulation circuitry block configured to provide a stimulation current to only the plurality of first electrodes;

    a second integrated circuit identical to the first integrated circuit comprising a second stimulation circuitry block configured to provide a stimulation current to only the plurality of second electrodes; and

    a conductive case for housing the first and second integrated circuits;

    wherein each of the first and second electrodes are operable as either an anode or a cathode,wherein any of the first electrodes is selectable to operate as an anode or as cathode, and wherein any of the second electrodes is selectable to simultaneously operate as the other of the anode or cathode, to pass a stimulation current from the anode to the cathode,wherein the first or second integrated circuit is configured to operate as a master integrated circuit, and wherein the other of the first or second integrated circuit is configured to operate as a slave integrated circuit to the master integrated circuit, andwherein bond programming of the first and second integrated circuits is used to configured the first or second integrated circuit as the master integrated circuit, and the other of the first or second integrated circuit as the slave integrated circuit, wherein one or more circuit blocks in the master integrated circuit are enabled while those one or more circuit blocks are disabled in the slave integrated circuit.
