Conforming inverted data store for low power memory

In this paper, we propose a ´conforming inverted data store´ scheme for reducing the power consumption in memory components. It reduces the power consumption by conforming memory contents to a precharging value of the memory. It selectively stores normal or inverted data so to reduce the total number of accessing bits different from the precharging value. In this way, bitline toggling during memory access is minimized and this ultimately contributes to a reduction in power consumption. We develop two practical implementations for the proposed method, that are vertical strip, and horizontal strip inversion schemes. Simulation results indicate that implementation of the strip-based inversion schemes contribute to a power reduction up to 50%.
