| — | Micron's record quarter shows how AI is squeezing the world's memory supply 高带宽内存。把多层普通 DRAM 芯片垂直堆 · 第 1 张术语卡 | It is the product that made Micron's quarter, and it competes with ordinary DRAM for the same factory capacity. HBM 每升级一代（HBM3E → HBM4），制造工序更复杂、占用的晶圆面积更大，所以单价也更高。美光的 HBM4 是 36GB、12 层堆叠的产品，供货给英伟达的下一代加速器。 |
