    Abstract: Methods, devices, arrays and systems for reducing standby power for a floating body memory array. One method includes counting bits of data before data enters the array, wherein the counting includes 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. This method further includes 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.
