Error-correcting code (ECC) has been widely used in DRAM-based memory systems to address the exacerbating random errors following the fabrication process scaling. However, ECCs including the strong form of Chipkill have not been so effective against Row Hammer (RH), which incurs bursts of errors discretely corrupting the whole row beyond the ECC correction capability.
