Scientists at the Physics and Engineering Department of the UK’s Lancaster University published a new paper describing ULTRARAM. A Low-Energy, High-Endurance, Compound-Semiconductor Memory on Silicon. I think this tech is a game changer but I still have my doubts. Let us discuss 0:00 Intro 0:30 RAM 4:00 SSD 11:00 UltraRAM 17:30 Doubts * RAM (Dynamic RAM) * Fast access with capacitors * random access * requires power to be refreshed * Flash NAND (SSD) * Pros fast random access (FTL) * Block storage * Requires high voltage (20V to erase/ 7.5 to program) * Low durability endurance which then (write amplification + garbage collection ) * UltraRAM uses a new novel approach to the memory cell design that only need 2.5 V to program/erase, low power which saves the memory cell lifetime https://www.sciencedirect.com/topics/engineering/fowler-nordheim-tunnelling * High endurance program/erase last longer * High retention * GC/WA not required * Limitations: still we know very little https://onlinelibrary.wiley.com/doi/10.1002/aelm.202101103 By Music Sorter at English Wikipedia, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=47090851 Become a Member on YouTube https://www.youtube.com/channel/UC_ML5xP23TOWKUcc-oAE_Eg/join 🔥 Members Only Content https://www.youtube.com/playlist?list=UUMO_ML5xP23TOWKUcc-oAE_Eg Fundamentals of Database Engineering udemy course (link redirects to udemy with coupon) https://database.husseinnasser.com Introduction to NGINX (link redirects to udemy with coupon) https://nginx.husseinnasser.com Python on the Backend (link redirects to udemy with coupon) https://nginx.husseinnasser.com 🏭 Backend Engineering Videos in Order https://backend.husseinnasser.com 💾 Database Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXjD0HOzN7P2tgzu7scWpl2 🎙️Listen to the Backend Engineering Podcast https://husseinnasser.com/podcast Gears and tools used on the Channel (affiliates) 🖼️ Slides and Thumbnail Design Canva https://partner.canva.com/c/2766475/647168/10068 🎙️ Mic Gear Shure SM7B Cardioid Dynamic Microphone https://amzn.to/3o1NiBi Cloudlifter https://amzn.to/2RAeyLo XLR cables https://amzn.to/3tvMJRu Focusrite Audio Interface https://amzn.to/3f2vjGY 📷 Camera Gear Canon M50 Mark II https://amzn.to/3o2ed0c Micro HDMI to HDMI https://amzn.to/3uwCxK3 Video capture card https://amzn.to/3f34pyD AC Wall for constant power https://amzn.to/3eueoxP Stay Awesome, Hussein
