There was another paper last year that showed something similar, and it went into way more detail on what TRR actually is. TRRespass: Exploiting the Many Sides of Target Row Refresh https://arxiv.org/pdf/2004.01807.pdf Memory controller mitigation of RowHammer can work pretty well, if one actually has it turned on. Which is unfortunately rarely the case even in 2021.

From the blog-- >> This is likely an indication that the electrical coupling responsible for Rowhammer is a property of distance, effectively becoming stronger and longer-ranged as cell geometries shrink down From the paper (bottom of page 13)-- >> ... we saw mappings from [1] that we used for this work. This suggests that the published findings about distance >1 Rowhammer are simply a result of not taking the correct mapping into account. Given that the patters we found appear to be distance 2 attacks, our industry partners were skeptical about them. These bits tell a much bigger story to…
