A method for conserving power in a device. The method generally includes the steps of (A) generating a polarity signal by analyzing a current one of a plurality of data items having a plurality of data bits, the polarity signal having an inversion bit indicating that the current data item is to be stored in one of (i) an inverted condition and (ii) a non-inverted condition relative to a normal condition such that a majority of the data bits have a first logic state, wherein reading one of the data bits having the first logic state consumes less power than reading one of the data bits having a second logic state, (B) selectively either (i) inverting the current data item or (ii) not inverting current the data item based on the inversion bit and (C) storing the current data item in a plurality of single-ended bit cells in the device.
