It is entirely clear how and why it happens.
It is a trade-off of density and coupling: the closer you get, the higher the parasitics. But if you stay far apart, you have low density (expensive). You also likely need different caching, error correction, and refresh settings.
The concept of parasitic write induced loss is really old in memory. Happens in NAND flash too. It is perhaps surprising that attacks like rowhammer never happened before. Or maybe we never knew?
