🚀 2. [Business Strategies & Future Plans]
- AI Inference Demand Recognition:
- Transition to AI inference is triggering exponential growth in concurrent users and token processing volume.
- Insufficient HBM capacity for KV Cache (Key-Value Cache) is causing workloads to offload sequentially to high-performance DRAM and SSDs.
- AI server computing loads are dispersing across general servers and edge devices, structurally expanding demand across HBM, premium DDR5, and eSSD.
- DRAM Business Strategy:
- Customer Commitments: Completed securing customer demand through 2026 across all DRAM products, including HBM.
- HBM4: Finalized 2026 supply agreements with major customers; initiating commercial sales in Q4 2025 with volume expansion planned for 2026.
- 1c nm Transition: Currently under stable mass production; accelerating node migration in 2026 to widen product lineup and maintain cost competitiveness.
- NAND Business Strategy:
- Customer Commitments: Secured customer demand through 2026 for the entire NAND lineup.
- 321-Layer Node & eSSD: Executing node conversion investments to capture AI server opportunities; expanding supply of 321-layer-based TLC and QLC products in 2026.
- Manufacturing Infrastructure Operations:
- Securing new capacity ahead of schedule through M15X, where cleanroom opening and equipment move-in have commenced.
- Accelerating conversion of existing capacity toward advanced process nodes to address rising demand.
📝 Editor’s Comment (by K-STOCK Editor)
The company highlights a structural market shift where the transition to AI inference forces KV Cache offloading from HBM onto conventional DRAM and SSD storage. Recognizing this architectural evolution as an opportunity to broaden demand across high-bandwidth memory, high-density DDR5, and enterprise SSDs, management presents a strategy to respond to expanding AI memory demand through HBM4 rollout, accelerated 1c nm transition, and 321-layer TLC/QLC deployment.
Key monitoring variables going forward include the initial commercial delivery of HBM4 starting in Q4 2025 and shipment expansion of 1c nm and 321-layer products throughout 2026, as well as the timeline for M15X capacity ramp-up alongside adherence to CapEx discipline.
