Impact of Extremely Low Temperatures on 5nm SRAM Array Size and Performance

2025-01-24
Impact of Extremely Low Temperatures on 5nm SRAM Array Size and Performance

New research explores the effects of extremely low temperatures (down to 10K) on the size and performance of 5nm FinFET SRAM arrays. Researchers found that at cryogenic temperatures, the maximum array size is limited by wordline parasitics, not leakage current, and performance is governed by both bitline and wordline parasitics. This has significant implications for future low-power, high-performance computing, offering valuable insights for optimizing SRAM arrays in extremely cold environments.

China's 'Artificial Sun' Sets New Fusion Record: 1,006 Seconds of Plasma Confinement

China's Experimental Advanced Superconducting Tokamak (EAST), nicknamed the 'artificial sun', has achieved a groundbreaking milestone in fusion energy research. It sustained high-confinement plasma operation for an unprecedented 1,066 seconds, surpassing the previous record of 403 seconds (also set by EAST). This significant achievement represents a crucial step towards harnessing fusion energy – a clean, virtually limitless power source. The success is attributed to advancements in heating system stability, control system accuracy, and diagnostic systems. This breakthrough not only showcases China's leadership in fusion research but also offers hope for a cleaner energy future.

Conquering Dumb LLM Search Judges with Classic ML

The author explores using a local LLM as a search relevance judge, a cost-effective alternative to OpenAI. Individual LLM judgments are unreliable, so the article proposes combining multiple LLMs' assessments of various product attributes (name, classification, description, etc.) using traditional machine learning (e.g., decision trees) to improve accuracy. Experiments show this approach can predict human preferences and reveal the logic behind human labels, aiding search engine optimization.

Federal Court Rules Backdoor Searches of 702 Data Unconstitutional

A federal district court has ruled that backdoor searches of databases containing Americans' private communications, collected under Section 702, typically require a warrant. This landmark ruling, following over a decade of litigation, rejects the government's claim that such searches can be conducted warrantlessly. Organizations like the EFF have long argued this practice is unconstitutional, and the court's decision is a significant victory for privacy rights. The ruling calls for Congressional reform of Section 702 to prevent future abuses.

Physics Uncovers Critical Tipping Points in Chess Matches

Physicist Marc Barthelemy analyzed over 20,000 top-level chess games using interaction graphs to reveal crucial tipping points. Treating chess as a complex system, he measured the 'betweenness centrality' and 'fragility scores' of chess pieces to predict game outcomes. The fragility score of key pieces rises about eight moves before a critical turning point and remains high for approximately 15 moves afterward, revealing a universal pattern across players and openings. This research offers fresh insights into the complex dynamics of chess and provides new avenues for AI and machine learning.
