LPRAM: a low power DRAM with testability

To date all the proposal for low power designs of RAMs essentially focus on circuit level solutions. What we propose here is a novel architecture level solution. Our methodology provides a systematic trade off between power and area. Also, it allows tradeoff between test time and power consumed in test mode. Significantly, too, the proposed design has the potential to achieve performance improvements while reducing power. In this respect it stands apart from other approaches where the conventional wisdom of reducing power reduces speed.
