存储器供应持续紧张 SK海力士在电话会议上详细阐述了当前的供应状况。公司DRAM库存在第四季度出现大幅同比下降， 生产的产品被立即发货给客户，留给库存积累的空间很小。 SK海力士在最新财报电话会议上释放明确信号：存储器市场供应紧张局面将持续，公司正全力扩产高 端产品但仍无法完全满足客户需求，这一供需格局预计在今年下半年仍将延续。 SK海力士表示，第四季度DRAM库存同比大幅下降，产出后立即向客户发货，几乎没有库存积累空 间。公司预计随着时间推进至今年下半年，DRAM库存将进一步缩减，客户供应紧张状况可能持续一段 时间。 在高带宽内存(HBM)业务方面，SK海力士透露，尽管目前正在最大化生产HBM4，但仍难以完全满足 客户需求。公司目标是在HBM4市场获得压倒性份额，延续其在HBM3和HBM3E产品上的主导地位。 此外，公司对美国大规模制造扩张持谨慎态度，但已宣布将投资100亿美元在美国成立AI解决方案公 司，利用包括HBM在内的先进芯片技术为数据中心客户提供优化的AI系统。 公司进一步指出，DRAM库存预计将在今年下半年进一步收缩，这意味着客户供应紧张的情况可能还会 持续相当长时间。 在NAND闪存方面，SK ...

据DIGITIMES周二报道，在韩国近期举办的下一代半导体技术趋势研讨会上，成均馆大学教授Seok-jun Kwon指出，存储行业正经历超级周期，DRAM价格在短短几个月内飙升300-400%。然而三星、SK海力 士和美光无法满足全球需求，这为中国存储制造商创造了进入市场的机会。 Kwon强调，中国企业的扩张潜力不仅限于消费零售领域，还包括企业级市场。即使只占据5-10%的市 场份额，也足以为其未来增长积累动能。 中国企业若能在这一窗口期获得更多技术经验，将对全球存储芯片格局产生深远影响。 技术追赶速度超预期 中国存储制造商正以惊人速度追赶韩国领先企业。2025年初，当SK海力士供应第三代高带宽内存 (HBM3E)芯片时，长鑫存储科技(CXMT)仍在开发HBM2技术，但到2025年年中就有报道称其已跃进至 HBM3开发阶段。 Kwon指出，CXMT的加速进展不仅源于自身资金，还得益于地方政府和华为的投资。新技术测试不仅 在CXMT自有工厂进行，还经常在华为投资的广东和上海工厂开展，使公司能在内部扩大生产前识别可 行方案。这种模式让CXMT缩短了研发周期，快速实现技术创新的商业化。 市场窗口期的战略意义 存储芯 ...
