彼时，新兴技术正从边缘切入，重构存储生态。比如MRAM（磁阻存储器）兼具SRAM速度、DRAM密度与Flash非易失性，已在车规级MCU、工业控制器中商用，三星、台积电、英特尔等均在持续推进该技术进展。ReRAM（阻变存储器）单元面积小，读写速度是NAND的1000倍，同时功耗可以降低15倍。CXL（Compute Express Link）虽非存储介质，却是内存池化的关键。通过CXL，服务器可将多个DRAM/HBM模块虚拟为统一内存池，大幅提升AI训练效率。Intel、AMD、三星正推动其成为下一代数据中心标配。不过，新兴存储并非要“取代”DRAM或NAND，而是填补其无法覆盖的“价值缝隙”。未来将是“传统+新兴”的分层共存格局。

Are you the kind of person that thinks a big, clunky TV on the wall ruins the aesthetic? The answer isn't no TV, it's the Samsung Frame TV.

The A/D bits exist entirely for the operating system's benefit. The Accessed bit tells the OS which pages have been recently used, enabling page replacement algorithms to choose pages to evict when memory runs low. The Dirty bit tells the OS which pages have been modified and must be written back to disk before eviction; clean pages can simply be discarded and re-read from disk later.，更多细节参见91视频
For this story, WIRED reviewed dozens of NASA documents, including backup plans and contingencies for emergencies, and spoke to more than a dozen people, including three astronauts who’ve visited the ISS, and no one seemed that freaked out. One astronaut said the most worrisome scenario that actively crossed his mind in orbit was getting a toothache. The ISS has had some emergencies, including a first-ever medical evacuation in January, but generally things have been remarkably stable. In fact, one of the most impressive things about the ISS is that nothing very dramatic has ever happened to it. No experiment has gone too haywire. It hasn’t been hit by an asteroid.
