Have you ever wondered why it takes time for computers to load programs or video games? Also, ever wonder why your computer uses both DRAM as well as SSDs when they both are used to store data?
Well, most of that time is spent moving data from a hard drive or SSD into DRAM or Dynamic Random Access Memory, which is the working memory inside your computer. In this video, we're going to take a very deep dive into DRAM. We'll see how it connects to other parts of your computer, and then we'll explore how DRAM can store gigabytes of data in nanoscopic capacitors. After that, we'll cover the three main operations of DRAM: Reading, Writing, and Refreshing. And finally, we'll dive deep into some more complex aspects of DRAM that make it so amazingly fast such as folded DRAM architecture. We'll also learn what burst buffers are, and why there are so many banks of DRAM memory cells.

  • If you want to support us, then liking the video, writing a small comment, and sharing this video with others on Twitter, Reddit, Facebook, WhatsApp, or elsewhere help a TON! Doing this will enable us to create much more in-depth content on how computers work! Why is it called Dynamic Random Access Memory? Also, why didn't we just call it RAM or just Memory throughout the video? Well, Random Access, means the computer can access any section of data with an equal amount of time before the data is read or written compared to any other section. The opposite is Linear Access Memory, which like a cassette tape. It's 'Dynamic' because the data cells lose charge over time, and thus have to be refreshed multiple times a second. Finally, we didn't call it RAM, because there are many types of RAM. SSDs are technically NVRAM [Non-Volatile RAM] Cache memory in the CPU is SRAM [Static RAM], GPUs use VRAM [Video RAM], which is VERY close in design to DRAM, and additionally there lesser known ones like MRAM [Magnetoresistive RAM] , and many more. Also, why not SDRAM [Synchronous Data RAM]? Because all DDR 1,2,3,4,5 is SD, and non-SDRAM for computers is obsolete by 20ish years- although I'm sure there is non-SD RAM for other applications. Also- did you spot that we use a DDR4 motherboard? That's because we had to purchase a motherboard and do a very thorough and destructive teardown, and thus we didn't have funds to splurge on the more expensive DDR5 motherboard.

In high school most students would simply ignore this material and wouldn’t remember it in a week.

    • Knowing how this stuff works can also be absolutely essential in optimizations. API's are fantastic for fast development and increased overall compatibility across hardware/software configurations, but being familiar with how the bare metal works, at least in theory. Computers today have so much memory, speed, and storage available to them, people get used to the idea of just brute forcing their work and setting higher minimum requirements than necessary. Case in point, Rollercoaster Tycoon.

However CE students have the advantage to know CS easily and not be victimized of improper education.

  • To the team behind this channel and all the computer explanation videos, Thank you, people, so much for making these videos. One of my hobbies and autistic "Special Interests" is computers as my brain works more like one, and it just makes sense to me. However for the longest time I was looking at all these parts as I took apart my computers and stuff, not knowing just how within 100 years, we went through such a technological Renaissance that began with literal light bulbs and so far has us manufacturing devices nearing on the size of atoms. It was such a confusing and intimidating subject to learn about because either it's years into a course on electronics in general, or just it doesn't make sense to me. But these videos explain it simply and effectively, assisted with the 3d modules in the video. I watch at 1x speed because your pace is perfect for me to be able to digest the information you just gave without being a drawling slog to get to the next point. These videos make it much easier to conceptualize how things work. Which is something not many other resources online can say. Thank you, team, for making these, they're my favorite videos so far.

    • Yep the Bios is loaded first which tells the CPU what channels and address all your hardware is on the motherboard a Bios is a roadmap to the Motherboard for your CPU, than it loads the boot loader and than the operating system that tells the processor the addresses to all directories and programs on your computer so the operating system is a map of the hard drive or SSD and shows your CPU the operating system your directory structure and prints it out in a easy to understand user interface for the end user you.
