1. A method of reducing standby power for a floating body memory array having a plurality of floating body memory cells storing charge representative of data, said method comprising:

  • counting bits of data before data enters the array, wherein said counting comprises counting at least one of;

    a total number of bits at state 1 and a total number of all bits;

    a total number of bits at state 0 and the total number of all bits;

    or the total number of bits at state 1 and the total number of bits at state 0;

    detecting whether the total number of bits at state 1 is greater than the total number of bits at state 0;

    setting an inversion bit when the total number of bits at state 1 is greater than the total number of bits at state 0; and

    inverting contents of all the bits of data before writing the bits of data to the memory array when the inversion bit has been set.
