From what I understand, it arises from DRAM manufacturers, interested in maximizing profits as much as possible, have been pushing the limits of how small they can make the RAM chip's features, and then backing off slightly until they felt ram was reliable "enough", but Rowhammer et al demonstrate it's very easy to cause bit flipping?
- markhahn 3y ago"maximize profits" and "best product for customer" are dual. you specifically want small chip features - or don't you like speed, power efficiency, and low cost?
- throwaway48476 3y agoThe point of engineering is trade offs. No one is trying to make a worse DRAM.
- rocqua 3y agoThey push the size to the limit, and stop when random writing is unlikely to cause any bitflips. Stopping at the point rowhammer would be unlikely would be stopping earlier. As others said, this isn't just about profits. It's about being able to compete on costs (i.e. being able to survive at all) and to compete on the best performance. This places the problem less at singular manufacturers and more at the whole industry.
