自动驾驶汽车未来需标配300G内存

自动驾驶汽车未来需标配300G内存

最近美光的消息有点多

1. 自动驾驶将带来“存储爆炸”
美光 CEO Sanjay Mehrotra 预测，随着汽车从基础辅助驾驶转向 L4 级自动驾驶，单车的 DRAM 需求将从目前的 16GB 飙升至 300GB 以上。这意味着汽车将成为像服务器一样的数据中心级移动终端。

2. 机器人是下一个增长点
美光认为机器人的计算平台需求与 L4 级自动驾驶车高度相似。为了处理复杂的 AI 任务，每个机器人同样需要约 300GB 的 DRAM 以及海量的 SSD 存储，这为存储芯片厂商开辟了全新的蓝海市场。

3. 美光的技术路线：首发 1γ LPDDR5
为了抢占汽车市场，美光正在准备生产业界首款汽车级 1γ (1-gamma) LPDDR5 DRAM。这表明美光试图通过更先进的制程工艺和车规级可靠性，在高性能汽车内存领域确立领先地位。

4. 对 HBF 技术持谨慎、观望态度
相比于韩国巨头（三星、SK 海力士）积极推动 HBF（高带宽闪存） 并计划 2027 年量产，美光的态度更为冷淡。美光认为 HBF 虽然容量大，但在写入速度、功耗和数据保存方面存在短板，目前仍处于早期阶段，商业价值有待观察。
