Hi! It seems that it is easy to induce DRAM bit errors by doing repeated reads from adjacent memory cells on common hw. Details are at
https://www.ece.cmu.edu/~safari/pubs/kim-isca14.pdf . Older memory modules seem to work better, and ECC should detect this. Paper has inner loop that should trigger this. Workarounds seem to be at hardware level, and tricky, too. Does anyone have implementation of detector? Any ideas how to work around it in software?
