报告指出,NAND Flash制造商主要通过降低产能利用率和推迟工艺升级来实现减产,这一决策背后有三大驱动因素: 智能手机和笔记本电脑等核心消费电子产品的出货量持续低迷,同时企业IT投资的放缓也抑制了企业级SSD需求的增长。 其次,自2024年第三季度以来,NAND闪存价格持续下跌,供应商对2025年上半年的需求前景持悲观态度,长期的...
SSD主控为NAND闪存提供了多个数据通道,每个通道可以有多个NAND颗粒,这样的话就可以通过交错(Interleave)最大程度的优化主控与NAND之间数据的相互效率。比如,下图所示,主控需要连续对一个通道上所有的NAND闪存进行写入(Write)操作,在Interleave功能的帮助下,同一个通道上的NAND闪存形成了一个最大通道利用率的流水线(Pipelin...

【NAND闪存过剩 消息称三星、SK海力士、美光等制造商计划今年减产以稳定价格】《科创板日报》24日讯,如今全球NAND闪存持续供过于求,相应市场面临严峻挑战,除了企业级SSD有动能支撑外,其他终端产品销量均普遍不如预期,供货商库存持续上升,订单需求下降。三星、SK 海力士、铠侠、美光均已开始研究NAND闪存减产计划,从而缓解...
(See: Researchers use ultrasound to improve SSD storage density.)Over the next few years, vertical NAND will be the first in a series of density-boosting enhancements that help push solid state storage prices down towards HDD levels. The gap between the two isn’t expected to close entirely,...
be saved. Modern drives use V-NAND, allowing cells to be stacked atop one another. The more cells present on the PCB, the more capacity the drive will have to offer. NAND-based storage such as SSDs has error-correcting code (ECC) to check all data is written and read without errors....
How to increase the storage capacity of the 3D NAND in the future? Although the industry has moved beyond 128-stacked WL structure with CuA (or PUC or COP or Xtacking) concept, the 3D NAND storage devices face a lot of challenges now such as a reduced cell string current, in...

UFS:Univeral Flash Storage,我们可以将它视为eMMC的进阶版,是由多个闪存芯片、主控、缓存组成的阵列式存储模块。UFS弥补了eMMC仅支持半双工运行(读写必须分开执行)的缺陷,可以实现全双工运行,所以性能得以翻番。 UFS早前被细分为UFS 2.0和UFS 2.1,它们在读写速度上的强制标准都为HS-G2(High speed GEAR2),可选...
