A method for conserving power in a device is disclosed. The method generally includes the steps of (A) storing a plurality of data items in a plurality of bit cells in the device such that a majority of the bit cells holding the data items have a first logic state, wherein reading one of the bit cells having the first logic state consumes less power than reading one of the bit cells having a second logic state; (B) generating a polarity signal by analyzing the data items, the polarity signal indicating that the data items are stored in one of (i) an inverted condition and (ii) a non-inverted condition relative to a normal condition; and (C) driving at least one of the data items onto an external interface of the device in the normal condition during a read operation based on the polarity signal.
