Seoul – Samsung Electronics and SK Hynix, the world’s top memory-chip makers, are on track to eclipse Taiwan Semiconductor Manufacturing Co. in memory-related profitability for the fourth quarter. This would mark the first time in seven years that Samsung and SK Hynix jointly lead the segment in quarterly margins, according to industry insiders in Seoul.
Analysts point to firmer DRAM and NAND pricing and a healthier demand mix as the main drivers behind the expected shift.While Samsung and SK Hynix are poised to post stronger memory profits, TSMC remains the global leader in pure-play foundry capacity and faces a broader market environment.
Observers say the anticipated swing highlights a broader realignment in the chip sector, with memory specialists gaining leverage as AI workloads and data-centre needs push demand for high-performance memory.
Key players at a glance
| Company | Area | Q4 Profitability Outlook | Notes |
|---|---|---|---|
| samsung electronics | Memory | Higher profitability expected | DRAM and NAND pricing improving; favorable mix anticipated |
| SK Hynix | Memory | Higher profitability expected | Benefiting from robust NAND and DRAM demand |
| Taiwan Semiconductor Manufacturing Co. (TSMC) | Foundry | Still dominant overall; memory profits may trail this quarter | Leading pure-play foundry; broader market dynamics at play |
Why the shift could endure
Industry watchers say the pivot reflects evolving demand patterns as data centers expand and AI compute raises the bar for memory performance. The timing aligns with tighter supply and strategic pricing moves across memory suppliers, which could sustain higher profitability beyond a single quarter.
Looking ahead, the balance between memory supply and the pace of AI-driven demand will shape margins for the rest of the year. Investors are watching how capex plans from leading memory firms translate into longer-term profitability.
Evergreen insights
The memory profit surge signals a potential shift in the semiconductor landscape, with memory specialists gaining relative strength. Firms may adjust capital allocation to further optimize DRAM and NAND output, sustaining pricing power in a competitive market.
As AI and data-centric services grow, the importance of memory efficiency and memory bandwidth rose to prominence, perhaps redefining product roadmaps and partnerships. Global supply chains will also feel the effect as memory-related capacity investments influence equipment demand and timeline choices.
Context and related reporting can be explored through industry updates from major players and market analysts. TSMC quarterly updates and Samsung Newsroom offer broader perspectives on sector dynamics.

1. Market‑wide Drivers Behind the Profit Surge
| Driver | Impact on Samsung & SK Hynix | Relative affect on TSMC |
|---|---|---|
| AI‑driven demand for high‑bandwidth memory (HBM & GDDR) | +22 % YoY revenue in HBM2E and GDDR6X segments | Minimal; TSMC’s memory fabs represent <5 % of total capacity |
| NAND flash rebound after 2024 inventory correction | NAND shipments back to 9.8 M pcs/quarter (up 18 %) | NAND is a small, non‑core offering for TSMC |
| DRAM price recovery (≈ $40/GB for 12‑inch wafers) | Gross margin improves to 48 % (vs 42 % in Q3) | Limited exposure; TSMC’s DRAM fabs are underutilised |
| Geopolitical supply‑chain diversification | New fabs in Pyeongtaek (SK Hynix) and Si‑Gong (Samsung) reduce lead‑time risk | TSMC continues to rely on high‑cost 3‑nm logic line capacity |
