Researchers at the Korea Institute of Science and Technology (KIST) have published a technical paper on using Rutile TiO2 as a post-ZrO2 dielectric platform for next-generation DRAM capacitors. As DRAM technology advances into sub-10 nm nodes, capacitor scaling faces challenges due to footprint loss and thickness limitations. Rutile TiO2 is proposed as a viable alternative to ZrO2, offering high permittivity for sub-0.3 nm equivalent oxide thickness (EOT) while maintaining process simplicity. The paper discusses the integration pathways for low-temperature rutile stabilization and leakage control strategies to make Rutile TiO2 a scalable DRAM dielectric platform.

Samsung and SK hynix warn AI-driven memory shortages could last until 2027 and beyond, as HBM demand explodes — customers already reserving supply years ahead, while the wider DRAM market begins to tighten

Samsung and SK hynix are warning of AI-driven memory shortages potentially lasting until 2027 and beyond, with HBM demand surging. The companies are struggling to meet demand as customers reserve supply years in advance, impacting the broader DRAM market. The shortages are fueled by the need for high-speed memory in AI infrastructure, particularly HBM, which is challenging to manufacture. Despite efforts to develop alternative memory technologies, the demand for existing memory remains overwhelming, prompting companies to invest in expanding production capacity. The memory crunch is part of a larger trend of resource shortages in the tech industry due to the rapid growth of AI infrastructure.

Global memory shortage expected to get worse before it gets better

The global memory shortage is expected to worsen, with reports indicating that DRAM shortages may persist until the end of the decade. Major manufacturers like Samsung, SK Hynix, and Micron are investing in expanding production facilities, but the additional capacity won't be fully operational until 2027 or later, leading to a multi-year supply gap. The rise in AI infrastructure demand for high-bandwidth memory is prioritizing production over traditional DRAM used in consumer devices, causing further supply constraints. Analysts predict a shortfall in production growth compared to demand, potentially extending the memory shortage until 2030, resulting in continued high prices for consumers.
