According to a report from Nikkei, Japanese memory manufacturer Kioxia has ended production cuts amidst a recovery in the memory market and has secured new bank credit support. The company’s plants in Yokkaichi, Mie Prefecture, and Kitakami, Iwate Prefecture, have restored their production lines to 100% capacity, focusing mainly on NAND flash production.

With improved business conditions, creditor banks have reportedly agreed to refinance a maturing loan of JPY 540 billion (roughly USD 3.43 billion) and have established a new credit line totaling JPY 210 billion (roughly USD 1.33 billion).

Kioxia had previously implemented production cuts in October 2022 due to sluggish demand for smartphone products, reducing output by over 30%. The planned launch of new production lines at the Kitakami plant, originally scheduled for 2023, has been postponed to 2025.

The improved market environment is reflected in Kioxia’s financial report for January to March 2024, where the company achieved a net profit of JPY 10.3 billion, ending six consecutive quarters of losses. Demand for smartphone and personal computer chips has bottomed out and is starting to recover, while orders related to data centers have increased.

As per a previous TrendForce report, Kioxia’s Q1 output was still affected by production cuts from the previous quarter, resulting in a modest 7% QoQ increase in shipments. However, rising NAND Flash prices led to a 26.3% QoQ rise in revenue to $1.82 billion. Kioxia expects to grow Q2 revenue by approximately 20%, supported by increased supply bits and more flexible pricing, which will further expand enterprise SSD shipments.

Per the same report from Nikkei, led by a banking consortium including Sumitomo Mitsui Banking, Mitsubishi UFJ Financial Group, and Mizuho Bank, Kioxia’s improved performance has led to relaxed loan terms and agreement on refinancing along with new credit limits. Additionally, the banks will assist in funding for equipment upgrades.

According to TrendForce’s latest memory spot price trend report, China’s 618 shopping festival has limited effects on demand, slowing down the digestion of existing inventory, causing DRAM and NAND Flash spot prices to slide further. However, DDR5 has been performing relatively better than older products such as DDR3 and DDR4 in sales. Details are as follows:

DRAM Spot Price:

Spot prices continue to decline. China’s 618 shopping festival is generating a more significant extent of purchase sentiment regarding smartphones due to huge price slashes, while other end products, having yet to exhibit any signs of recovery in demand, have slowed down the digestion of existing inventory. Generally speaking, DDR5 has been performing slightly better in sales, while older products, such as DDR3/4, are sustaining a larger decrement due to transitions of platforms. Mainstream packaged DDR4 1Gx8 2666MT/s saw a price drop of 0.84% (from US$1.904 to US$1.888) this week.

NAND Flash Spot Price:

Spot prices for NAND Flash are maintaining a slow depletion. The recent 618 e-commerce promotions have proven to be confined in efficacy towards overall market demand, where the enervation seen from transactions of consumer products continues to aggravate the inversion between contract and spot prices. 512Gb TLC wafer spots have dropped by 1.74% this week, arriving at US$3.328.

Recently, Samsung Electronics announced that the development of its 8nm eMRAM has almost been completed and process upgrades is underway as planned.

According to a report from WeChat account DRAMeXchange, as a new type of non-volatile memory technology based on magnetic principles, eMRAM falls under the category of embedded MRAM (Magnetoresistive random-access memory). Compared to traditional DRAM, eMRAM offers faster access speeds and higher durability. Unlike DRAM, it does not require data refreshing, and its write rate is 1000 times that of NAND.

Due to these characteristics, the industry holds a positive outlook on the potential of eMRAM, especially in scenarios that demand high performance, energy efficiency, and durability.

Samsung Electronics is one of the main producers of eMRAM and is dedicated to promoting its adoption in the automotive sector. In 2019, Samsung developed and mass-produced the industry’s first eMRAM based on 28nm FD-SOI. After achieving the production capability of 28nm eMRAM, Samsung reportedly plans to mass-produce 14nm eMRAM in 2024, 8nm in 2026, and 5nm in 2027.

Samsung is confident about the application of eMRAM in future automotive uses, stating that its product’s temperature tolerance has reached 150-160°C, which can fully meet the stringent requirements of the automotive industry for semiconductors.

In recent years, the proliferation of big data and artificial intelligence applications has generated massive memory demands and placed higher requirements for memory technologies. Against this backdrop, new memory technologies have continuously emerged, among which SCM (Storage Class Memory) is a representative, which combines high-speed read and write performance of DRAM with the persistent storage capability of NAND flash, potentially addressing issues of small capacity, volatility, and high cost associated with DRAM. Key SCM products include phase-change memory (PCM), resistive RAM (ReRAM), magnetoresistive RAM (MRAM), and nanotube RAM (NRAM).

Aside from Samsung, companies like Kioxia and ByteDance have also acted vigorously in the new memory field this year. In April, Kioxia’s CTO Hidefumi Miyajima stated that compared to competitors developing both NAND and DRAM, Kioxia is at a competitive disadvantage in terms of business diversity, making the cultivation of new memory product business like SCM a necessity. With this goal in mind, Kioxia reorganized its “Memory Technology Research Laboratory” into the “Advanced Technology Research Laboratory.”

In March, it was reported by South China Morning Post that ByteDance invested in a Chinese memory company Innostar, becoming its third-largest shareholder. Innostar focuses on the R&D of new memory technologies like ReRAM and related chip products covering three categories: high-performance industrial control/automotive-grade SoC/ASIC chip, computing-in-memory (CIM) IP, chip and system-on-memory (SoM) chip.

As AI-related semiconductors has been driving the demand of High Bandwidth Memory (HBM), the NAND flash market now also feels the vibe. According to industry sources cited by Business Korea, the NAND Flash market competition is intensifying, while memory giants Samsung and SK Hynix are ramping up their efforts to improve the performance and capacity of NAND products.

In April, Samsung confirmed that it has begun mass production for its one-terabit (Tb) triple-level cell (TLC) 9th-generation vertical NAND (V-NAND), boasted to improve the bit density by about 50% compared to the 8th-generation V-NAND, with the number of layers reaching 290, according an earlier report by The Korea Economic Daily.

Based on the report on May 20 by Business Korea, Samsung intends to dominate the AI SSD market with its 9th Generation V-NAND, targeting the development and sampling of ultra-high capacity 64 terabyte (TB) SSDs in the second quarter.

In mid-May, Samsung even revealed the target to release advanced NAND Flash with over 1000 layers by 2030. According to an earlier report by Wccftech, the South Korean memory giant plans to apply new ferroelectric materials on the manufacturing of NAND.

On the other hand, the current HBM3 supply for NVIDIA’s H100 solution is primarily met by SK Hynix, leading to a supply shortfall in meeting burgeoning AI market demands. After establishing its leadership in HBM, it is reported that SK Hynix now aims to dominate the AI memory market in NAND as well, according to Business Korea.

It is worth noting that SK Hynix recently achieved a breakthrough with the development of “Zoned UFS 4.0” (ZUFS 4.0), an on-device AI mobile NAND solution tailored for AI-capable smartphones, which is scheduled to start mass production in the third quarter, according to TheElec.
