Abstract:Leakage currents in on-chip SRAMs: caches, branch predictor, register files and TLBs, are major contributors to the energy dissipated by processors in deep sub-micron technologies. High leakage also increases chip temperature and some SRAM-based structures become thermal hotspots. Previous work has addressed major sources of SRAM leakage in memory cells and bit-lines, making remaining SRAM components, in particular large drivers, the primary source of leakage. This paper proposes an approach to reduce this sou… Show more
