A method of power optimization in a memory is disclosed. The method generally includes the steps of (A) dividing a plurality of bit cells in a design of the memory into (i) a plurality of first rows storing programmed data and (ii) at least one second row storing only padding data, (B) adjusting the design such that a second power consumption in each of the second rows is lower than a first power consumption in each of the first rows and (C) generating a file defining the design as adjusted.
