Summary of SK hynix: 1) What does the company do? It is a global producer of semiconductor memory, specializing in DRAM and NAND Flash that power IT devices like computers, phones, and servers. 2) How do its products work? DRAM stores data using tiny capacitors and requires periodic refreshing to keep data, providing fast volatile memory. NAND Flash stores data in non-volatile memory cells and preserves data without power, serving as durable storage. Both chips are mounted in devices to enable fast processing and data retention. 3) How is the company different from competitors? It ranks as the second-largest memory chip maker with a broad product portfolio and strong technology, backed by the SK Group, giving it scale, resources, and global reach. 4) What is the company's goal? To become the world’s best semiconductor company by meeting diverse customer needs and leading in memory technology.

SK Hynix is seeking US approval to ship more chipmaking equipment to China, and ties a planned US factory to that approval, Reuters reported, citing people familiar with the matter. Its shares have fallen 20% this month, heading for their worst month since the July Nasdaq listing. Its US unit, Solidigm, wants to install NAND flash memory equipment at SK Hynix's Dalian plant in China. It is seeking an export licence for tools from Lam Research, Applied Materials, and KLA Corp. Expanded output in Dalian would help fund a new US NAND factory. The Commerce Department revoked licence exemptions for SK Hynix and Samsung last year. SK Hynix holds a 2026 licence for Dalian with limits on equipment quantities; approval for 2027 is pending. Chip stocks fell worldwide on hotter US inflation, AI spending worries, and Chinese competition.
Micron Technology has become the 11th largest company in the world, with a market cap of $1.12 trillion, driven by demand for memory chips in AI data centres, smartphones, and PCs. One analyst argues two rivals could overtake it within five years. Advanced Micro Devices (AMD), valued at $970 billion, saw second-quarter revenue rise 50% year over year to $11.5 billion. Data centre revenue jumped 107% to $6.7 billion, and AMD's share of the server processor market rose to 34.5% from 27.3%. SK Hynix, valued at $780 billion, holds 50% of the high-bandwidth memory market against Micron's 18%. It trades at 11 times earnings against Micron's 25, and analysts expect long-term earnings-per-share growth of 82%, versus 65% for Micron.
Elon Musk said China can often scale a product it has mastered beyond the rest of the world combined, but advanced memory "will be harder to solve." He cited lithium batteries and solar, and called SpaceX a rare exception. His comments on X came as memory stocks slid. The selloff erased a combined $108 billion from the market values of Micron, SK Hynix, and SanDisk after ChangXin Memory Technologies (CXMT) reported chip-design advances. Musk said low-power memory for phones and laptops follows a common standard that China "seems to be solving fast." High-bandwidth memory and stacked designs are tougher. TrendForce data put CXMT's share of global DRAM revenue at 9.5% in the second quarter, up from 7.6% in the first. Micron fell 3.88% to $989.04 on Monday and lost another 1.40% after hours.
Asian stocks fell on Tuesday as tech shares plunged on fresh worries about the AI investment boom. Seoul's Kospi dropped more than 6%, Tokyo's Nikkei 225 lost nearly 3%, and Taipei fell more than 2%. SK hynix and Samsung slid after reports that China's CXMT had made progress on technology to boost memory density. It plans a new server-memory product by the end of the year, the reports said. Broadcom chief executive officer Hock Tan likened the AI buying frenzy to gambling. He noted that OpenAI still loses money, though it reported annualised revenue of $50 billion in September. Traders are awaiting tech earnings and key US data. Brent crude fell 1.1% to $105.52 despite Houthi attacks on Saudi Arabia.
SK Hynix unveils lightweight H-TPU to shrink power and die area in enterprise SSD controllers. 25 seconds ago October 12, 2026 SK Hynix has shared details about a processor design built to cut down on power use and chip space in modern SSD controllers. At the International SoC Design Conference (ISOCC) 2026 in Incheon on October 12 Vice President Koo In-je introduced the Hynix Transaction Processing Unit, or H-TPU. It's a custom-made programmable core built inside SK Hynix's own labs. The goal is to handle the repetitive I/O tasks that solid-state drives need to run smoothly. Now most SSD controllers use general-purpose Arm CPU cores to manage things like read and write commands, metadata, and buffer control. As SSDs get faster and handle tasks at once, companies add more of these cores. That makes the chip bigger and uses more power. The problem? Most of the work is simple. Follows a set pattern. The H-TPU is designed for that kind of work. It has a four-stage pipeline. Runs tasks one after another, which fits perfectly with how SSDs operate. The H-TPU is small enough that more than 100 of them can be placed across the controller chip. Only the ones needed for a specific task turn on. The rest stay off to save power. SK Hynix says one H-TPU uses 2.5 percent of the power and takes up around 4 percent of the space that a regular general-purpose CPU core would use. The main host CPU is still there for jobs like handling errors, recovering from problems, and making top-level decisions. SK Hynix also built software tools to make it easier for engineers to program the H-TPU cores. That includes a compiler for the job. The company plans to roll out the H-TPU in its next-gen enterprise SSD controllers. After that, it will be used in Storage Next. SK Hynix's system for AI-focused fine-grained storage access with 512-byte blocks. It will also appear in bandwidth flash products expected next year. This move is part of a trend in the industry: building specialized chips for storage as AI and data centers demand more efficient storage solutions.
