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。

But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.
