Samsung Announces: Production Cease for This Memory Chip Type! No More New Orders!
The high profit margins of advanced memory products have prompted Samsung to discontinue LPDDR4 and LPDDR4X production, reallocating more capacity to DDR5 and HBM. This also marks the official entry of these two mainstream memory products, which have been in mass production for over a decade, into their End-of-Life (EOL) phase.
According to Korean media reports, Samsung will stop accepting all new orders for LPDDR4/4X starting April 17, 2026, and will no longer accommodate customer follow-up procurement requests. Considering the timeline for final orders, production of LPDDR4 and LPDDR4X is expected to continue until the end of 2026, with production line conversion scheduled to commence in the first quarter of 2027. At that point, LPDDR4/4X will be completely phased out, with all capacity shifting to LPDDR5, LPDDR5X mobile DRAM, and HBM (High Bandwidth Memory).
Samsung's Core Rationale for Discontinuing LPDDR4 Series
The primary reason behind Samsung's planned discontinuation of the LPDDR4 series lies in the significantly higher profit margins of HBM (High Bandwidth Memory) and advanced DDR5 products. Coupled with the undersupply of advanced memory amid the AI wave, Samsung aims to allocate limited wafer and capacity resources entirely to higher-margin product lines, no longer maintaining production capacity for low-profit legacy products.
LPDDR4 and LPDDR4X have been the dominant memory solutions for consumer electronic devices such as smartphones, tablets, and laptops over the past decade. Samsung's discontinuation will directly impact Samsung's own memory business division as well as numerous external customers.
Impact on Memory Pricing and Market Dynamics
Furthermore, the spot prices for these chips are expected to become more volatile. Samsung's LPDDR4X memory quote surged from $6 per chip in March 2025 to $28.5 per chip in January 2026—an increase of nearly four times in less than a year.
This price volatility stems from several factors:
- Supply Constriction: With Samsung exiting the LPDDR4 market, the available supply will decrease significantly
- Demand Stickiness: Many legacy systems still require LPDDR4 components, creating artificial demand
- Transition Costs: Manufacturers face higher costs to redesign products for newer memory standards
- Inventory Hoarding: Customers may stockpile components ahead of the official EOL date
Samsung's Broader Production Strategy Beyond LPDDR4
Samsung's production halt plan extends beyond just LPDDR4. As early as February, reports indicated that Samsung Electronics would cease manufacturing 2D NAND flash memory at its Line 12 facility in the Hwaseong campus. This production line originally had a monthly capacity of 80,000 to 100,000 12-inch wafers. The reduced NAND capacity in South Korea is expected to be compensated by increased production at Samsung's Xi'an factory in China. Samsung is currently upgrading its 3D NAND production lines in Xi'an to manufacture next-generation NAND products.
The strategic shift in NAND production reflects several industry trends:
- 3D Stacking Advantages: 3D NAND offers better scalability and performance compared to 2D planar structures
- Cost Efficiency: While 3D NAND has higher initial costs, it provides better long-term economics
- Technology Maturation: 2D NAND has reached its practical limits in terms of scaling and performance
- Market Segmentation: Different NAND types serve distinct market needs (2D for low-cost applications, 3D for high-performance)
Industry-Wide Shift: Competitors Also Phasing Out Legacy Products
Across the current memory market, Samsung is not the only company discontinuing legacy memory products. In March, Kioxia issued two separate discontinuation notices, announcing the phasing out of Thin Small Outline Package (TSOP) and some Floating Gate and BiCS Flash Gen3 products.
The specific timelines for Kioxia's discontinuations include:
- TSOP Products (8Gb-64Gb):
- Final purchase forecast deadline (customer's last order quantity): May 30, 2026
- Final purchase order deadline: September 15, 2026
- Final shipment date: March 15, 2027
- Floating Gate and BiCS Flash Gen3 Products (based on 32/24/15nm processes for SLC/MLC/TLC):
- Final purchase forecast deadline: September 30, 2026
- Final shipment date: December 31, 2028
- This includes wafers, BGAs, TSOPs, eMMC, UFS, and standard SD cards
Technical Drivers Behind NAND Technology Transition
The rapid evolution of NAND Flash technology in recent years has been driven by several factors:
- Limited Cleanroom Space: As fabs approach physical limits, manufacturers must optimize production for the most profitable technologies
- Economic Viability: Compared to mainstream TLC (Triple-Level Cell) and QLC (Quad-Level Cell) architectures, MLC (Multi-Level Cell) offers the lowest unit value
- Capital Efficiency: NAND manufacturers are pursuing economies of scale and better capital efficiency
- Technology Roadmap: The industry is actively concentrating resources on TLC, QLC, and DRAM while gradually phasing out MLC products
Market Implications and Opportunities
As major players exit legacy markets, opportunities emerge for other companies to fill the void. For domestic memory chip manufacturers, this may represent a valuable market window. By potentially filling the mid-to-low-end memory market gap left by Samsung's exit, they could expect an order surge in the second half of 2026. This would undoubtedly be another positive development for the current hot memory market, especially given the continuously improving performance of domestic memory chips.
The current market landscape presents several strategic considerations:
- Supply Chain Diversification: Customers are seeking multiple suppliers to mitigate single-source risks
- Technology Transition Window: The period between EOL announcement and actual discontinuation creates opportunities for alternative suppliers
- Performance Parity: As domestic manufacturers close the performance gap with established players, their market acceptance increases
- Cost Competitiveness: Legacy products, while technically inferior, often offer compelling price points for certain applications
Technical Specifications Comparison: LPDDR4 vs. LPDDR5

- Profit Pool Concentration: Memory manufacturers are focusing on the most profitable segments of the market
- Technology Acceleration: The transition from one memory generation to the next is happening faster than ever before
- Geopolitical Factors: Supply chain diversification is influencing production location decisions
- Sustainability Considerations: Newer memory technologies often offer better power efficiency, aligning with environmental goals
Market Response and Future Outlook
The memory industry is expected to undergo significant transformation in the coming years:
- Price Volatility: Legacy memory components may experience extreme price fluctuations as supply diminishes
- Design Inertia: Some product segments will continue using legacy memory due to cost constraints
- Innovation Acceleration: The vacuum created by discontinued products will drive innovation in alternative solutions
- Market Consolidation: Smaller players may acquire discontinued product lines to serve niche markets
- Regional Shifts: Production capacity will increasingly move to regions with competitive advantages
Conclusion
Samsung's discontinuation of LPDDR4 production marks a significant inflection point in the memory industry. By focusing on high-margin DDR5 and HBM products, the company is strategically positioning itself to capitalize on the AI-driven demand surge. While this transition will create short-term challenges for legacy system manufacturers, it also presents opportunities for alternative suppliers to fill the market gap. The broader industry trend toward discontinuing legacy memory products reflects the rapid pace of technological advancement and the increasing importance of memory performance in next-generation computing applications.
