Alleviating Memory Refresh Overhead via Data Compression for High Performance and Energy Efficiency.

DRAM memory suffers from increasingly aggravating refresh penalty, which causes significant performance degradation and power consumption. As memory capacity increases, refresh penalty has become increasingly worse as more rows have to be refreshed. In this work, we propose an effective refresh approach called Compression-Aware Refresh (CAR) to efficiently mitigate refresh overheads. We apply a da...
