We have Brazilian users in this forum too, and they can certainly find things (one of them not long ago managed to find a component marking that I couldn't...) so your country should not be an obstacle.
As mentioned above the Wikipedia is a good start. For more in-depth, follow the references from there and to lecture slides of EE courses, and then go find datasheets and read them if you really want to know more.
Ive never said I cant find anything I search for. It was clear from my post I was having trouble finding information on this particular topic. Ive never created a thread or asked anything here without spending some time trying to learn it first.
Perhaps I should try to make clear what happened.
Usually, when Im searching for something as common as RAM or SSD drives, a quick google search yields the necessary information to very basically covers one's curiosity. Googling is no effort and I understand that some people might feel the way they presented here in this thread. I felt the same way on different occasions and different forums.
This time it did not.
I searched and read about the first twelve pages about it (that came on the google result). None of them gave me the answers I was looking for.
That was rather strange given the topic.
Then, I went to youtube and it lead me into a trail of how the whole process of recording data for computers developed and not actually how the insides of the RAM or SSD worked. To be 100% honest there was a video made by gentlemen with a heavy Indian accent that was very hard for me to understand so I couldnt learn much. The videos BrianHG posted here did not appear on my search (thanks for posting them, they helped a lot).
After watching 4 videos and none of them explained about the SSD or how the data actually stayed there after disconnecting I was surprise that I had spent a couple of hours with no result.
So I came to the forum.
Really?
He didn't word his post as "hey I'm interested in this but can't find info, can you help me?" which would have been no issue, but downright "I can't find any so it must not exist and I call BS until you point me straight to it". If that's not trolling...
It might have been intended as a joke but didn't come out as one, it came out as "I can't be bothered to look it up, do it for me".
Really, that is what you got from my message?
You say I didnt ask: hey I'm interested in this but can't find info, can you help me?"
This is the first line of my post: Ive been trying to learn how does RAM and SSDs work. All I get is the manufacturing process of the PCBs for the RAM sticks or Flash Drive units.
Then I say nearly exactly what you described: Can someone direct me to a website about that?
So you would rather me say: "guys, I did no research, tell me how an SSD works?"
I wrote a post with the results Ive found. Even describing what showed up that was not directly related and showing that I took the time to try to learn it.
I was truly surprised that I could not find a clear answer to that question, I wrote that in the post. This does not mean I expect any 5 minutes of googling to bring instantaneous knowledge to me. It means that something was up, either the way I was searching for it (If I knew the expression "floating gate" it would have been a 2 minute search, but I didnt and it wasnt) or some other thing.
When I said the joke at the end about living in the matrix you actually think I was serious? That is what you got from my post? That I dont believe RAM and SSDs are real?
I specifically told you I was not trolling. I went to the trouble of respectfully answering you and telling that nowhere I saw that DRAM looses its memory just after powering it down.
I'm not having the problem you do. If I type "How does a RAM work?", all the results are in English. I don't need any special settings. I even tried other languages. Comment fonctionne une RAM? give me all the results in French. Wie funktioniert ein RAM? gave me all German. Even Russian is no problem: Как работает RAM?
Let me tell you something funny happened to me some months ago:
Since moving to Brazil from the US using google became a demanding task. I switched all my settings from Chrome, Gmail, YT to USA and english in a effort to bypass the region/location filters and get results in english (which usually are more reliable than Portuguese in my experience). Google and YT continue to change my location and manipulate the results even after I specifically set them not to. Typing "LCD" on YT results in a array of brazilian videos.
What is funny is that this did not happen when I was living in the US and visiting Brazil. My IP address is the same, my computer is the same and my settings are the same...
Now, how in the world is that done? One thing is tracking your physical location and changing results in the hopes of giving you a better experience, another is to KNOW that I dont LIVE (not where I am but where I live) in the US anymore and force the results to local ones.
This was specially horrible during a immigration crises that happened last year in the US. I would google about it, read all the relevant content and somehow everything was twisted - I know this is starting to sound like conspiracy but hold on - Some results holding specific images, graphics and numbers would just not appear. My friends would tell me "Look, this happened" and I would google that in many different ways and not get the result they were getting. Then, they would send me the link. Of course, after that, if I googled their link, it would now show up.
Also, all the propaganda and adds I receive are ALL in portuguese. For sometime I used a american VPN service and guess what? All the adds continued to be in portuguese.
