Thanks for the interesting historical reference! As you state, this type of problem is not new, and as noted at [1] e.g. Intel have taken this seriously on their Xeon lineup for a while. It's a shame (LP)DDR4 standards did not make Target Row Refresh mandatory. From the FAQ at [2]: I have a phone with LPDDR4 memory. Am I safe against Drammer attacks? Again, we don’t know. Chances are that your DRAM comes with the Target Row Refresh (TRR) mitigation, which makes it harder – but still not impossible, in theory – to induce bit flips. Moreover, TRR for LPDDR4 is optional, so your DRAM manufacturer may have decided to drop this technique and leave you vulnerable.
