It happened because at some point in the past (around 10 years ago I believe), the memory vendors decided that it was ok to design product with known "pattern sensitivity", because...I suppose they made more money that way and no customer complained loudly. Pattern sensitivity in memory chips is a very old problem, and previously was treated as a fatal design error, fixed and the affected chips used for parking lot infill. But today every chip sold is affected. Basically the same as Boeing and the MAX, just fewer people killed.

You seem to know more about this than I do. Where might one go to read more about this? Are there whitepapers, design docs, other resources which could be used to assert positively that the industry used to consider this a defect?
