first_img SK Hynix stated that 3D DRAM development can utilize foundry processes

SK Hynix stated on the 9th that the development of the next-generation memory 3D DRAM semiconductor can utilize foundry processes. The day before, at the 2026 SK Hynix Future Forum held at the Supex Center in the Icheon campus, Vice President Kim Kyung-hoon and Son Ho-young presented the main technical directions for 3D DRAM, including the use of logic foundry processes for DRAM peripheral circuits, maximizing data bus bandwidth, and ultra-short distance transmission.3D DRAM is the next-generation DRAM that vertically stacks the originally planar storage cells to improve integration. The two stated that achieving this technology requires addressing not only design and heat dissipation issues but also challenges in fine interconnections, bonding, and process integration in the packaging field. As the boundaries between front-end and back-end packaging, foundry, and memory technology converge, collaborative optimization beyond existing fields will become more important. Son Ho-young mentioned that 3D technology is changing the technological boundaries between wafer fabs and packaging, and it is necessary to establish an optimization and new collaboration system that transcends existing fields alongside innovations in advanced packaging technology.In a related presentation, Professor Shin Chang-hwan from Korea University stated that 3D DRAM is not only about the vertical stacking of chips but also a technology that breaks the boundaries between memory and logic. As device miniaturization approaches its limits and the time and power consumption associated with data movement between systems and memory increases, the shift to 3D technology is inevitable. He proposed a 3D integrated design framework that links materials, devices, packaging, and architecture through artificial intelligence. SK Hynix President Kwon Oh-joon, in his speech, remarked that the past memory market resembled a straight road where the competition was about who could run faster, but now it resembles a constantly changing curve, making it important to grasp the speed and direction of external environmental changes and adapt flexibly in addition to internal capabilities.

first_img Brazilian Bank Expands Cryptocurrency Services, Regulatory Framework Takes Shape

Brazilian banks are expanding their cryptocurrency services for customers. According to Folha de S.Paulo, Brazil's largest asset management bank, Itaú, now offers 15 types of cryptocurrencies, including Bitcoin, Ethereum, and the US dollar stablecoin USDC, through its investment app. Brazil's largest fintech company, Nubank, has listed 28 types, and Banco do Brasil, the most profitable state-owned bank in Brazil, has seen transaction volumes exceed 11 million reais (approximately 2.1 million USD) since launching direct purchase services for Bitcoin and Ethereum in January of this year.However, customer cryptocurrency transactions have not entered the banks' balance sheets. A document from the central bank dated March 2026 shows that Brazilian banks hold zero virtual assets on their books. Over the past year, Itaú, Bradesco, Santander, Banco do Brasil, and Nubank have all expanded their cryptocurrency product lines, while the Brazilian cryptocurrency market has also reached record sizes. According to data from the Brazilian Federal Revenue Service, Receita Federal, Brazilians transferred 505.5 billion reais (approximately 98.7 billion USD) through cryptocurrencies in 2025, more than five times that of 2020, with corporate transactions accounting for 98.3%.This move by banks coincides with the implementation of regulations. In 2022, Brazil passed the "Virtual Asset Legal Framework," granting regulatory authority to the central bank. Three resolutions issued in November 2025 require any institution allowing customers to trade, hold, or send cryptocurrencies to obtain a license, meet minimum capital requirements, and segregate customer accounts, with a compliance deadline of October 30, 2026.

first_img The United States' crackdown on Iranian oil tankers has driven up oil prices, while Bitcoin has fallen nearly 1% to $79,700

Bitcoin price fell nearly 1% to around $79,700, as escalating conflicts between the United States and Iran pushed oil prices higher. The U.S. Central Command confirmed on Saturday that it struck three Iranian oil tankers located near Halk Island, Jask, and the Gulf of Oman. Admiral Brad Cooper stated that if Iran attacks U.S. vessels, the U.S. will impose a higher economic cost.The U.S. Central Command updated maritime blockade data, stating that since resuming operations on July 14, it has redirected 92 merchant ships, disabled 3, and boarded 2 for inspection. Oil prices rose by 1% in both the U.S. and European markets, with WTI at $92.72, marking a cumulative increase of over 6% in the past seven days. The rise in oil prices could exacerbate global inflation, making it more difficult for central banks, including the Federal Reserve, to cut interest rates.Additionally, the U.S. employment data for August released last Friday was stronger than expected, reinforcing expectations for an interest rate hike by the Federal Reserve. However, Trump immediately posted on Truth Social calling for a rate cut, stating that a strong nation means lower interest rates. This uncertainty may dampen risk appetite for Bitcoin and the broader market. Furthermore, late Sunday night, the Liquid Network, used by exchanges as a settlement layer, suffered a $320 million attack.
