If it really does match the performance of DRAM, then this seems huge. Surely it can't be true? Maybe it's only true for small amounts of memory?
- wmf 5y agoThere's plenty of previous work on NVM as main memory. This looks like an incremental improvement. All real NVM chips I'm aware of are slower than DRAM so the only way to match DRAM performance would be to use more chips which has packaging considerations. NVM is mostly theoretical since XPoint is mediocre and nothing else is available.
