在之前的文章中，几次都写到了HBM相关的内容，我们后面也将持续跟踪存储器市场，包括NAND 和DRAM。在这些文章中，我们会提供最近的存储器市场的数据，以及大机构的预测趋势，包括各 个厂商（包括长鑫和长江存储）的市场占有率、出货量、成品晶圆和晶粒的库存、晶圆出货量等。 这篇文章参考的内容主要来自UBS的研报和数据。我们参考的内容都会放到星球中。 三星与SK海力士对第二季度的指引反映出一定程度的需求前置，尤其是来自智能手机和PC客户的需 求。两家公司均预计2Q25 DRAM出货量将环比增长小于10%。对于NAND，三星预计Q2出货量环比 增长大概5%左右，而SK海力士则超过20%。 UBS维持对DDR定价在2Q25环比增长5%的预测，其中LPDDR5的势头持续强于DDR5和 DDR4/LPDDR4。对于NAND均价，UBS将Q2预测从+5%下调至+3%。尽管嵌入式NAND闪存需求仍 相对积极，但SSD价格上涨正面临客户更强烈的抵制。 展望2025年下半年，由于关税不确定性，存储厂商的能见度低于正常水平。UBS继续认为NAND闪 存需求更可能面临规格降级（或客户通过套件调整压低内容成本，本质相同）。因此，UBS预 ...
