res[i] = stack[stack.length - 1]; // 易错点5：用at(-1)兼容性差，优先用stack.length-1
I could definitely be reading too much into a six-second social video, but Cook's X post looks to me like the back of a MacBook. The video also shows a person manipulating the Apple logo with their fingers, which, to me, screams "touchscreen."

在传统存储产品方面，10nm以下DRAM制造工艺正成为主流，并逐步向7nm工艺突破，通过“FinFET架构+TSV技术”提升密度、降低功耗。3D NAND堆叠层数突破400层后，“垂直堆叠”难度加剧，厂商转向“水平扩展+架构优化”，比如三星V-NAND的阶梯式架构、Kioxia的BiCS架构，同时引入“HKC（高K介质+金属栅）”技术，解决高层数堆叠的漏电、散热问题，制造工艺从“层数竞赛”转向“架构+工艺”双重竞争。
