Samsung’s NAND chip project faces the biggest crisis in its history.

NAND Chip Prices Plunge

In October 2024, in the memory semiconductor market, DRAM prices remained stable, while NAND flash memory prices experienced a significant drop close to 30%.

Analysts believe that the decline, primarily in commodity products, is due to weak demand in the PC and mobile sectors.

Data shows that the average fixed transaction price for storage cards and USB commodity NAND flash memory products in October was $3.07, a decrease of 29.18% month-on-month.

NAND flash memory prices had been on an upward trend for five consecutive months since last October, followed by six months of stability, before turning downward in September.

The sluggish demand for TLC NAND Flash chips has led to price drops for SLC and MLC NAND, with the expected decline narrowing in November after significant price drops in September and October.

The average fixed transaction price for PC DRAM commodity products in October was $1.7, unchanged from the previous month.

DRAM prices have been on an upward trend since October of last year, with stability in May to July, a turn downward in August, and a sharp drop of 17.07% in September. Since then, prices in October have remained stable with no changes.

Due to reduced purchasing volumes by buyers and the confirmation of fourth-quarter contract prices, PC DRAM has shown a stable trend.

Retail Investors Trapped by Samsung Electronics

In October, the Korea Exchange reported significant differences in the behavior of retail and foreign investors in the South Korean stock market for the entire month of October.

Retail investors favored Samsung Electronics, purchasing stocks worth 4.2 trillion won (approximately $3.09 billion), while foreign capital showed a strong preference for SK Hynix, purchasing 745 billion won.

On October 2nd, Samsung Electronics’ stock price was 61,300 Korean won, and SK Hynix’s stock price was 169,100 Korean won.

However, by October 28th, Samsung Electronics’ stock price plummeted over 9% to a low of 55,700 Korean won during the trading day, while SK Hynix’s stock price soared, increasing by 15.9% to 196,000 Korean won.

The stark contrast in stock performance reflects different investor sentiments and market dynamics.

From the beginning of the year to today, Samsung Electronics’ stock price has fallen by about 26%, while SK Hynix’s stock price has risen by 30%.

In the first six trading days of October, retail buying was concentrated on Samsung Electronics, with a net purchase amount of 2.15 trillion won. This trend continued throughout the month, with the purchase amount reaching 4.27 trillion won by October 31st.

On the other hand, due to SK Hynix’s outstanding performance, foreign capital has shown a preference for the company.

The rise in SK Hynix’s stock price is attributed to strong third-quarter earnings and a positive future outlook.

Researchers point out that SK Hynix raised its profits for 2024 and 2025 by 2.2% and 4.5%, respectively, in the third quarter, while most other companies, including Samsung Electronics, saw no changes.

Samsung Electronics announced an operating profit of 3.86 trillion won for its semiconductor division in the third quarter, which was below the expected 4 trillion won.

Poor performance led to foreign capital continuously selling off Samsung Electronics’ stocks throughout October.

In contrast, SK Hynix’s strong performance and dominance in the HBM market have bolstered investor confidence.

It is predicted that SK Hynix will continue to solidify its dominant position in the HBM market during periods of slowing demand.

Samsung Electronics’ Storage Profit Margin at Approximately 22%

Comparing the third-quarter performance of Samsung Electronics and SK Hynix, it is evident that there is a significant gap in profit margins for memory business between the two companies.

SK Hynix’s operating profit is around 40%, while Samsung Electronics, although not disclosed, is estimated to be around 22%.

This means that SK Hynix’s leading position is very solid, and its management efficiency is much higher.

The competition between the two around HBM will become increasingly fierce.

Institutions estimate that Samsung Electronics’ storage division’s third-quarter profit was 5.3 trillion won, with a profit margin of around 22%, a decrease of 7% from the second quarter’s 29%.

Samsung Electronics was unable to supply NVIDIA and saw a significant decline in profitability as shipments in the Chinese market continued to increase.

SK Hynix benefited from the high demand for HBM, with third-quarter profits of 7 trillion won and a profit margin of 40%.

In the past, it was common for Samsung to have a profit margin of over 40%, while SK Hynix’s profit margin was around 20%; now, the opposite has occurred.

Samsung Electronics’ overall profit for the DS division in the third quarter was 3.86 trillion won, with a profit margin of 13%.

It is estimated that the profit for other divisions is approximately 5.3 trillion won, with non-storage losses of 1.5 trillion won.

Clearly, Samsung Electronics’ non-storage divisions are suffering significant losses, and the outlook is not optimistic.

Samsung plans to invest a cumulative total of 47.9 trillion won in its semiconductor business by the end of this year.

The storage division will focus on facility investments, shifting towards high-value-added products such as HBM and DDR5, as HBM prices are at least four times that of commodity DRAM products, enabling higher profits.

SK Hynix will have a cumulative investment of 10 trillion won by the end of this year and is expected to have 10 trillion won in equipment investment next year.

Next year’s investment direction will be to transform products, reduce the output of commodity products, and increase sales of DDR5 and LPDDR5.

Equipment investment will increase, but slightly decrease compared to this year.

Samsung Electronics Aggressively Chasing SK Hynix

In order to catch up with SK Hynix in HBM, Samsung Electronics is taking aggressive actions in hopes of regaining the industry’s top position.

It is expected that personnel and organizational adjustments will be implemented as early as this month, leading to significant changes within the company.

Samsung Electronics is focusing on high-profit storage products like HBM and has announced a competitive strategy for its current contract manufacturing.

As an integrated semiconductor company specializing in design, storage, and wafer foundry, there were previous concerns about technology leaks and customer competition, making it difficult to gain the trust of more customers.

Now, Samsung is preparing to abandon its previously held strategy by offering to cooperate with other wafer foundry companies to attract customers to use their HBM, thereby quickly improving storage performance.

On November 1st, at the 55th-anniversary ceremony of Samsung Electronics, the storage division leader stated that without change, there can be no innovation or growth.

The upcoming significant organizational adjustments and personnel changes are highly anticipated.

NAND flash memory chips Market and investment analysis

The plummeting prices of NAND flash memory chips are a complex phenomenon influenced by multiple factors. Here are some potential reasons and impacts:

1. Low Demand**: As you mentioned, low demand in the PC and mobile sectors is one of the main reasons for the decline in NAND flash memory prices. When there is a reduction in new product releases in these areas or a decrease in consumer purchasing power, the demand for storage chips also decreases.

2. Oversupply**: If the supply of NAND chips exceeds the demand in the market, it can lead to a price drop. This could be due to overestimation of market demand in the past or technological advancements that increase production efficiency, thus increasing supply.

3. Technological Advancements**: As technology evolves, producing higher-performance and larger-capacity NAND chips becomes more cost-effective. This can lead to a decrease in the prices of older technology chips as they are replaced by newer technologies.

4. Market Competition**: With more manufacturers entering the market, intensified competition can lead to price wars, which in turn can drive down prices.

5. Economic Environment**: Changes in the global economic environment, such as inflation and trade policies, can also affect the prices of NAND chips.

6. Inventory Adjustments**: Companies may adjust their inventories based on market conditions, which can lead to short-term supply and demand imbalances, affecting prices.

7. Product Lifecycle**: As new products are introduced, older products may be discounted to clear inventory, making way for new products.

The significant drop in the average fixed transaction price of storage cards and USB general NAND flash memory products in October, as you mentioned, could be the result of a combination of these factors.

A substantial decrease in prices can impact the profit margins of manufacturers and may also stimulate demand by offering lower purchase costs for consumers. However, prolonged low prices can affect the healthy development of the industry, causing some manufacturers to exit the market or seek new growth opportunities.

For investors and businesses, it is crucial to closely monitor market dynamics and adjust strategies to adapt to market changes. For consumers, this may be a good time to purchase storage devices, but it is also necessary to consider the risks associated with price fluctuations

Samsung Electronics Plans AND layoffs

According to industry sources, Samsung Electronics’ latest storage chip development roadmap indicates that the company plans to produce at least 400-layer cell vertical stacking vertical NAND by 2026 to maximize capacity and performance.

Samsung Electronics plans to adopt a new bonding technology, creating cells and peripheral devices on separate wafers, and then bonding them. This method will achieve “ultra-high” NAND stacks with large storage capacity and excellent heat dissipation performance, which are very suitable for ultra-high capacity SSDs in AI data centers. This chip is called Bonding Vertical NAND Flash, or BV NAND for short, and its bit density per unit area will be increased by 1.6 times.

Samsung Electronics plans to launch V11 NAND by 2027, further developing its stacking technology, with a 50% increase in data input and output speeds. The goal is to develop NAND chips with more than 1,000 layers by 2030 to achieve higher density and storage capacity.

SK Hynix has also begun the development of 400-layer NAND Flash and is currently developing process technologies and equipment, with the goal of achieving mass production by the end of next year and full-scale mass production by the first half of 2026.

Kioxia has indicated in its technology roadmap that the number of 3D NAND layers will grow at an annual rate of 1.33 times, reaching a level of 1,000 layers by 2027, with NAND chip density reaching 100 Gbit/mm²

Samsung Electronics undergoes four rounds of massive layoffs

Samsung Electronics to Implement Four Rounds of Voluntary Retirement, Contract Manufacturing Team to be Reduced by Over 30%.

According to a high-ranking official at Samsung Electronics on November 2nd, the first round of voluntary retirement will be offered to CL3 (Associate Manager level) employees who have worked for more than 15 years but have not received a rank in the last 5 years. The second round will be for employees who have worked continuously for over 10 years; if the target is not met, the third round will be expanded to all employees. It is reported that the final fourth round will be conducted as part of normal operations. The conditions for voluntary retirement are expected to include a compensation package totaling approximately 400 million won (currently about 2.064 million yuan), which includes a severance payment based on CL3 and four months’ salary of 380 million won.

Especially, the 8-inch contract manufacturing and technology team will see a reduction of over 30%. It is understood that Samsung is considering a proposal for voluntary retirement for unpaid employees. This comes after Samsung Electronics recorded a profit shock in the third quarter of this year due to a decline in competitiveness in its flagship semiconductor business, triggering a crisis theory within the group.

This is interpreted as part of a reform plan to overcome aging business environments and poor performance.

Samsung recently announced third-quarter revenue of 79.1 trillion won, slightly exceeding the expected 79 trillion won, and operating profit of 9.18 trillion won, which exceeded the expected 9.1 trillion won, but was significantly lower than the estimated 11.456 trillion won in operating profit by the London Stock Exchange. Samsung’s Vice Chairman and newly appointed head of the Device Solutions (DS) division, Jeon Yong-hyun, apologized rarely after releasing the performance guidance.

Among them, Samsung’s semiconductor division announced an operating profit of 3.86 trillion won (about 2.8 billion USD) for the third quarter, a 40% decrease from the previous quarter.

Although its memory chip division benefited from strong demand for artificial intelligence (AI) and traditional server products, Samsung stated that “inventory adjustments had a negative impact on mobile demand.” The company said it is also dealing with the issue of “increased supply of mature process products from China.”

Additionally, according to insiders on November 1st, Samsung Electronics has shut down over 30% of the 4nm, 5nm, and 7nm wafer contract manufacturing production lines at its Pyeongtaek 2 (P2) and 3 (P3) factories, and plans to expand the suspension of production to about 50% by the end of the year. The company intends to gradually halt production while monitoring customer orders.

Samsung will Import ASML High NA EUV lithography machine 2025.

According to reports, Samsung Electronics is preparing to Import its first High NA EUV (Extreme Ultraviolet) lithography equipment in early 2025, marking a significant advancement for the South Korean tech giant in the field of advanced semiconductor manufacturing. This cutting-edge technology, exclusively provided by Netherlands ASML, is crucial for processes below 2nm. South Korean industry observers anticipate that Samsung will accelerate the development of its 1nm chip commercialization.

Each High NA EUV lithography machine is priced at approximately $350 million (about 2.5 billion yuan), significantly higher than ASML’s standard EUV series, which ranges from $180 million to $200 million. The High NA system boasts a resolution of 8nm and a transistor density triple times that of the Low NA system, thus offering immense value.

According to relevant reports, Indicate that Samsung’s first High NA EUV equipment—the ASML EXE:5000 model—is expected to hit the market in early 2025. Given the complexity of semiconductor equipment installation, which often involves lengthy testing phases, the EXE:5000 is projected to become operational in the second quarter of 2025.

High NA EUV technology surpasses existing EUV systems by enabling the creation of finer circuit designs, making it suitable for chips operating below 5nm, such as CPUs and GPUs, which are system semiconductors. While standard EUV is effective for 5nm and below processes, High NA EUV can further achieve circuit dimensions below 2nm, thereby enhancing performance and reducing the number of exposures, which in turn lowers production costs. The latest research conducted by Belgium’s Interuniversity Microelectronics Centre (IMEC) in collaboration with ASML shows that a single High NA EUV exposure can produce complete logic and memory circuits.

This development signifies Samsung’s first foray into High NA EUV technology. Previously, the company had collaborated with IMEC on circuit processing research. Samsung plans to use its own equipment to accelerate the development of advanced nodes and has set a goal to commercialize a 1.4nm process by 2027, potentially paving the way for 1nm production.

Globally, competition among semiconductor giants such as TSMC, Intel, and Samsung is Competition heats up as they vie to secure High NA EUV equipment for processes below 2nm. Intel was the first to obtain the equipment in December 2023, followed by TSMC in the third quarter of 2024. Although Samsung’s order came later, achieving stable production could be the key to determining industry leadership.

Samsung plans to use the High NA EUV equipment it will receive in early 2025 for research purposes and intends to Import dedicated mass production equipment shortly thereafter. In a meeting with ASML in the third quarter of 2024, Samsung indicated that it would reconsider the number of High NA EUV equipment units it plans to purchase, which could reduce its initial order by two units. The company initially planned to Import the EXE:5000 in the fourth quarter of 2024, with follow-up models EXE:5200, EXE:5400, and EXE:5600 to be Imported over the next decade.

  • A1-rated cards need a minimum random speed of 1500 IOPS and a write of 500 IOPS. Obviously, these specs ensure smooth app performance for everyday tasks.
  • In contrast, an A2 rating requires a minimum of 4000 IOPS for random read and 2000 IOPS for write. Hence this makes A2 cards better suited for intensive applications, ensuring faster performance.

Durability & Reliability

Durability is crucial when selecting a Micro SD card. Meanwhile a reliable card protects your data in various conditions. Look for waterproofing, shock resistance, and temperature tolerance features to ensure the card functions well in different environments.
