$MU $DRAM $SNDK dont listen to all the bears talking you Kospi is down. They were already down following the US selloff Friday. Remember the KOSPI does not trade Friday night because they are a day ahead of us. $KORU is up a decent amount which shows bullish to start the week vs how they ended last week.

$SNDK not sure how monday will play out... Korea is down around 5% and the Korean Chip Stocks are down 9%...so im loaded with dry powder .... im still a believer in Sandisk. I had a great weekend...

Here is the link to the original, which I found it to be the best so far on upcoming HBF, led by $SNDK and $SKHY. https://www.theregister.com/storage/2026/07/30/gpus-could-explode-to-multiple-tb-with-new-storage-inspired-memory-tech/5281363

Bit technical, but a must read for $SNDK $SKHY traders as HBM-HBF combo could be the future. The Bottleneck: Current GPUs (HBM3e) max out at 96GB–288GB, forcing massive LLMs to split across hundreds of GPUs or offload data to slower RAM/SSDs. The Tech: Storage-inspired memory applies vertical 3D-stacking techniques (similar to 3D NAND flash) to high-density DRAM/Storage-Class Memory. The Breakthrough: Stacking memory 128+ layers high scales on-die GPU capacity to multiple Terabytes (1TB–8TB+) per chip at a drastically lower cost per gigabyte. Tiered Architecture: Ultra-fast HBM handles active matrix ops, while multi-TB 3D DRAM holds entire model parameters with near-nanosecond access. The Impact: Enables single-node workstation training for 100B+ parameter AI models, massive context windows, and lower datacenter power and hardware costs. $DRAM.X $MU $KORU
