The current miniaturization of DRAM circuitry doesn't really allow for a hardware fix for the RowHammer attack. During DRAM manufacturing a test similar to the RowHammer attack exists. This test has certain bounds for passing. If the bounds were tightened up to the level of perfection to prevent the attack it would drop the yield a considerable amount.
