The utility of this turns on a question whose answer is not readily apparent from skimming the paper: is this something that can be implemented purely in software? Or does it require a hardware mod? Because if it's the former then it could be a game-changer. If the latter, not so much.
- readams 5y agoThe paper uses a custom memory controller based on SoftMC implemented on an FPGA. The DRAM modules themselves are off-the-shelf. It appears you need precise control over DDR4 command timing that would not be possible with a normal memory controller. So it's hardware-only, though you could imagine adding this feature to memory controllers in the future.
- lisper 5y agoSure. but there's not much difference between that and just adding a regular old TRNG. A hardware design change is a hardware design change :-(
