=) Well... Not quite. ECC helps, for sure. But if you read the first security-oriented paper on row hammer (linked to in the one I sent earlier): http://users.ece.cmu.edu/~yoonguk/papers/kim-isca14.pdf They indicate that it simple ECC mechanisms are not adeqate to prevent all flips: "For example, SECDED (single error-correction, double errordetection) can correct only a single-bit error within a 64-bit word. If a word contains two victims, however, SECDED cannot correct the resulting double-bit error. And for three or more victims, SECDED cannot even detect the multi-bit error, leading to silent data corruption. Therefore, we conclude that SECDED is not failsafe against disturbance errors." With that said, I'm definitely planning on buying ECC from now on. tim _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
