[Goldman Sachs: High-bandwidth flash memory is expected to break the AI ​​"memory wall" with a potential market size of up to 150 billion US dollars] October 13th, Goldman Sachs released a research report on the 12th stating that with the rapid growth of AI reasoning demand, insufficient storage capacity is becoming an important bottleneck restricting computing power efficiency. New NAND technologies such as high-bandwidth flash (HBF) are expected to alleviate this "memory wall" problem and significantly reduce AI infrastructure costs. The bank estimates that when the GPU adoption rate reaches 15% to 50%, the potential market size of HBF can reach US$40 billion to US$150 billion. Goldman Sachs is optimistic about SanDisk and SK Hynix's HBF technology leadership and maintains a "buy" rating for the two companies; Samsung Electronics is also expected to benefit. In contrast, Micron maintains a "neutral" rating because its business focus is on DRAM and HBM, which directly benefits less.
