Based on the above-mentioned finding, as well as some of the studies already exists, in this paper we
proposed a simple and effective STT-RAM L1 cache counter-controlled data processing scheme aiming at
saving refresh energy. First, using STT-RAM as L1 cache is rarely less does before by other researchers.
Second, we propose a counter controlled scheme to adapt the use of STT-RAM as L1 cache in our
simulation.
