Refresh Now and Then

  title={Refresh Now and Then},
  author={Seungjae Baek and Sangyeun Cho and Rami G. Melhem},
  journal={IEEE Transactions on Computers},
DRAM stores information in electric charge. Because DRAM cells lose stored charge over time due to leakage, they have to be “refreshed” in a periodic manner to retain the stored information. This refresh activity is a source of increased energy consumption as the DRAM density grows. It also incurs nontrivial performance loss due to the unavailability of memory arrays during refresh. This paper first presents a comprehensive measurement-based characterization study of the cell-level data… CONTINUE READING
