Samsung Electronics and SK Hynix, the two dominant players in South Korea’s memory chip industry, have announced that they will extend the production lifecycle of DDR4 products until the end of 2026.
While DDR5 is widely regarded as the next-generation mainstream standard, unexpected market dynamics are reshaping industry strategies. A mismatch between supply and demand has driven a surge in DDR4 prices, prompting manufacturers to reconsider their original roadmaps. Both Samsung and SK Hynix have quietly delayed DDR4 phase-out schedules, signaling that the aging standard is experiencing an unanticipated “second life.”
Roadmap Adjustments
Samsung initially planned to wind down its 1z-node DDR4 DRAM production lines by late 2025. However, the company has now extended production through December 2026. SK Hynix has followed suit, also lengthening DDR4 output while boosting capacity at its Wuxi wafer fab to support customer demand.
Technology Context and Market Dynamics
DDR4 memory, first commercialized in 2014, has been in volume production for over a decade. Normally, with DDR5 gaining traction and capturing market share, a gradual reduction in DDR4 supply would align with the industry’s technology upgrade cycle. Yet, current market conditions tell a different story.
Since mid-2024, DDR4 spot prices have climbed sharply, in some cases exceeding those of DDR5—a rare instance of “price inversion.” TrendForce data shows that in June 2024, DDR4 16Gb spot prices averaged $7.01, higher than DDR5’s $5.85. By late August, the gap widened further, with DDR4 rising to $8.59 while DDR5 remained at $6.17. For manufacturers, maintaining DDR4 production lines under these conditions translates to stronger margins and greater near-term profitability.
Drivers of the Price Inversion
The key driver lies on the supply side. In early 2024, Samsung, SK Hynix, and Micron had already signaled reductions in DDR4 capacity. Shortly thereafter, surging demand for high bandwidth memory (HBM) reshaped capacity allocation. Because HBM consumes nearly three times more wafer resources per chip compared to standard DRAM, expanding HBM production inevitably constrained DDR4 output. Panic buying across the supply chain further intensified the upward price trend.
On the demand side, sectors such as industrial control systems and telecommunications infrastructure continue to rely on DDR4 due to stability and compatibility requirements. At the same time, the global build-out of AI data centers has fueled DRAM demand broadly, ensuring that DDR4 still retains a significant role in the server market.
Outlook
By extending DDR4 production, Samsung and SK Hynix aim to stabilize near-term supply and capture elevated profit margins. However, industry consensus remains that DDR5 adoption is inevitable. Over time, DDR5 will secure dominance across computing applications, reflecting both the natural progression of semiconductor innovation and the industry’s commitment to meeting increasingly complex system demands.
