Do you live at a very high altitude with a significant amount of solar radiation, or at an underfunded radiology lab or perhaps near a uranium deposit or a melted down nuclear reactor? Because the average machine should never see a memory bit flip error at all during its entire lifetime.

Then how do you explain all the bugs in the software I write?!

It truly is a cosmic mystery :)

Bit flipping can be the byproduct of bow the system components harmonize. Role hammer RAM also has the same affect. [0]

> Furthermore, research shows that precisely targeted three-bit Rowhammer flips prevents ECC memory from noticing the modifications.

Doesn't exactly sound like a use case for ECC memory, given that it can't correct these attacks. Interesting though, I'd have thought that virtual addresses would've largely fixed this.
