that.
Most people don't realize how amazing it is that so much information can be kept on such a small card.
more like "kids today will never understand the struggle"
@@godlaster3182 Exactly, they don't know how good they have it XD
Sort of a miracle they work at all.
People take these things for granted. I remember when we could store 8k in about that space, but with parallel access it was 100x the size.
Then you think about it , its crazy that we gone from smacking rocks together to make to fire to now this .
I can't even imagine what humanity will be capable in the next 100 years .
We went from smashing rocks, to being able to force them to think if these things processed in such specific way, a.k.a CPU
Let that sink in....
"We" haven't, "they" have.
Most modern humans still wouldn't be able to make a fire if they were stranded with no lighter or matches.
They should make clear ones they look very cool.....
That's a really good idea! I like the sound of it! 👍
Would look pretty cool but I think that light getting in might upset the chips.
@@pvc988 I noticed your username! ... I love wearing PVC! ... Do you like it too, or does it refer to something else? ... Perhaps your name in Paul Vincent Clarke? 🤣
@@marcse7en No, it refers to something completely different. It's just a slight modification of my real nickname when I was a kid.
@@pvc988 PVC kinksters, like myself, will get the wrong idea! 🤣
So.... what's inside the flash array? (large black rectangle).
I always check my micro SD cards like this before I use them to see if they're genuine
I would love to see an ARM under the laser
Too little magnification. If you zoomed in more, you could see the microscopic size of the Leyden's jars where data is stored
Bu şekilde taktığında çalışacak mıydı? Keşke onuda gösterseydin
Good work, thanks 👍!
why not use sulphuric accid to ech it after laser is done its job?
That looks like an original EVO from Korea. Those can be reprogrammed to a different CID. The new ones from Philippines are not reprogramable.
The video would have been loads better if the part had been full frame while it was being lasered
I wonder if this still works😳
A masterpiece by mankind.
Is it a cheapest solution or why the small chip is conected with the wires? It's not possible to make "BGA like " connection?
BGA implies a PCB. There's no PCB here, the IC and wires are all suspended in plastic.
How do you think a BGA chips' silicon is attached internally? :P These bond wires go from the silicon to a PCB, here it is done directly because it is cheaper but mostly because there's no space to stick a 'large' BGA chip on top.
Look on this channel for the SSD laser decap video, the controller chip in that video is a BGA chip and shows how those too have bond wires inside.
@@someguy4915 Yeah, I saw few videos already and it seems to be standard method of silicone - pcb/terminals connecting method.
I've always wondered what's inside the microSD card. Now I know.
nice. 👍
next with fake sdcard. 🤔
Why that laser didn't harm chips and other components??
Low power mod
Metal components partially reflect laser and also can dissipate more heat. But silicon chips got destroyed thought.
@@NikolayIslentev ohh !
0:16 Then proceeds to print "256GB" on it.
So THAT's how they do it....
Alien technology
Memory
And we can buy them as low as 10 bucks.

Christ what bad "music" thank the Lord for a mute button.
ㅓㅜㅑ 이건 너무 야한데?
Interesting, but dosen't tell me anything about HOW, it does what it does 🤔
So, Not very informative ✝️🇺🇸🤔
The channel Branch Education has an excellent video titled: "How do SSDs Work" both SSDs and SD cards use flash memory.
So interesting so see the hidden electronic components. Please show more items.
Of course, what semiconductor would you like to see in the next video?
@@a1elektro1 most of them will be interesting. The 555 timer is very popular, simple and small. Even some larger transistors or a old 286-486 intel CPU if you can find any. The older chips were 14-30nm so should be able to see more of what’s going inside.
@Etienne Thank you for the comment and subscribe to my channel. In the next video, I will try to show something from this.😉
@@etienne6641 i doubt they're as small as 30nm. i don't wanna fact check it now but i'm pretty sure "newer" xeons had something like 40nm and the esp32 uses 30nm process. again not sure about this info
@@king_james_official I also speak from memory many moons ago so have to check. My point is the bigger the nm size the better the chance we will see more detail of the chip 😀
Always wondered what goes inside one of those. So much storage on something so tiny, micro SD cards are almost magical
im curious as to what a high capacity one looks like (512GB, 1TB+, etc.) are they any different or more dense or what
Just bigger flash memory area
Most of the visible differences will be due to more modern manufacturing technology. The wire bonding will be replaced with CSP, chip scale packaging. The memory die won't be encapsulated individually, it will depend on the outer packaging to block light. The PCB traces may look different to support higher data transfer rates.
Since the memory package is close to the size limit already, it will consist of smaller memory cells that each hold more bits, and that are stacked with more layers.
Every semiconductor junction can act as a photodiode, an LED, or as a solar cell whether or not that behavior is wanted. The voltages and spectrum will be a function of the bandgap.
If an unprotected chip is exposed to high enough frequency light, it will react. EPROMs took advantage of this effect and were intentionally erased with special UV lights. If you left the labels or cover off, the EPROMs would eventually be unintentionally erased by environmental near UV, or even violet light.
smaller microSD cards may be bigger ones with parts of the memory disabled after manufacturing due to partially broken memory chips. As far as I know this is a common practice in this industry
Bigger flash chip and bigger address bus
@@maeanderdev
It is. It’s called “binning”. All chips are essentially identical when they come out of the development phase.
Chips at this stage are called “dies” (plural; singular form is “die”) and are tested: those that meet peak specs are binned highest, while those that fail to meet these peak specs are tested at different spec levels.
For flash memory, there is only two criteria: data capacity and data transfer speed.
Data capacity is simple: if the die does not meet the peak capacity, it’s binned for the highest capacity it reached, rounded down to the nearest binary exponential (2^n, so 64GB, 128GB, 256GB, 512GB or 1TB if the peak spec is 2TB). If the workable capacity is below the minimum specs, however (or the array is unaddressable), the die is discarded.
Data transfer rate is usually made up of four sub-criteria: sequential read speed, sequential write speed, random access read speed and random access write speed.
For SD cards, there are a handful of different speed standards, each with different requirements and different tiers. Dies are only rejected if they fail to meet *any* standard (usually because data tranfer for that particular die is far too unstable to safely store data on). Otherwise the SD card it’s cast into will be labeled with the speed classifications it meets.
The controller needs to be taken into account as well, but it’s usually made with a much more mature fab process (the array itself may use 5nm while the controller may use 7nm or even 10nm) to ensure maximum yield rate. It has *several* criteria, *and all must be met!* If even one criteria fails, the controller die is tossed.
Another thing to note: the smaller the die, the more dies can be developed per wafer.
I remember thinking a 100k floppy disk had a lot of storage space... 64 gig like mind blown
I used to hate storing mp3 in multiple floppy disks. CD burners changed my world lol and now micro SD/SSDs are insane compared to it all.
What interests me even more is what happens, when those memory cards breakdown without any visible damage.
I'm wondering if it still works. If yes you could cover it with epoxy resin.
I was wondering the same thing. I am guessing no, either from the heat or from possibly any radiation the laser may give off. Then again I know nothing about lasers.
Silicon totally got destroyed. No way it would work.
@@NikolayIslentev Do you mean that in that the chemistry changed?
@@DoubsGaming More like laser melted internal structures. Chips not supposed to be gray, they normally shiny with visible internal circuits. Acid decapsulation method is less destructive and sometimes being used in reverse engineering of ICs.
@@DoubsGaming Laser IS radiation, electromagnetic radiation at a specific wavelength.
It looks like it didn't destroy it at first look, but only a test will tell.
To really see you need an electron microscope.
Do you have the slightest idea of how much an electron microscope costs?
@@ahmedelged4894 Sure I saw them on ebay
I need this for BGA solder pad clean-up :)
You mean BGA fryier?
Most peoples: It's a plastic card with golden contact pins;
Tech nerds: It's multi-layer micro PCB with flash RAM & controller chip.
I like sandisk
so impresive we can buy that for 5e...
What's inside ...a fingernail?
Super! Thank you very much!
holy shit. wow. i am just in awe. the laser is wow. and the inside of the memory card is wow. thanks for the video.
Where is memory? I want to see the transistors.
Never knew there were smd mlcc capacitors inside microsd cards.
Probably for input decoupling.
It's remain me that many years ago a floppy disk has 5 mb storage only. And now we can have 1 gb storage in a tiny memory card.
When did floppy disks have 5mb? They were 1.44mb mostly.
you can see that it appears there are 2 big die stacked, and the one little controller die, along with some decoupling caps. I wonder how many they can stack now. 4? more ?
Nice ❤
Incredible! Great job!
sounds like the song that starts playing is saying "Toe nail jail, tony tony tony"

Is it possible to use a 6W fiber machine?
Wow Great work 👍👌
Fuck it would be cool to have one of these in an epoxy block on my keychain or desk.
I have no idea how it works, but I know that it has limits, I think that even today they have exhausted the possible speed and they are only changing for economic reasons, mostly only the cover and they deliberately make old machines unfit to buy new ones even if it suits them the old one, because only text is written on it, see Pentium-4, on which Skype cannot be installed, for example, even if it were only used for messages.
Wow, there was a microchip inside, who would guess.
I got started in computers in the days of the IBM 360. Most bank mainframe computers had 64 KB of main memory or less.
I wonder if it'll work in this state and if it works, then what was the purpose of black coating?
Well, like protection and to make into a standardised format.
Isolation?
I'm so fkin dum
@@tracerhax Take your award for Most Honest UA-cam Commenter 🏆
@@fluffy6818 really, an award of all time
Without explaining what the components inside are? This video could have been so much more than the two minute time waster you have achieved.
Why do you stop short of decaping the IC? That's where the most interesting stuff is.
Nice music, perfect ways to explain what on the screen... Total waste of my watching time
so amazing that the chips are not flip chips, but instead, wire bonded to the pcb
oh oh i know this one, its memory!
Is it some kind of 8051chip (smaller rectangle) ...?
Thanks for your Sharing
I would prefer a slightly bigger design but more reliable...
hrm. i was expecting brain matter of slaughtered orphans
alien technology wow
Great, but remove the stupid music for goodness sake
is it work after de capuslation ?
I was expecting to see a bunch of 1's and 0's
thank you!
Now I can go back to sleep
so cool!!!
Thank you!
Amazing
Great!
wow...
cool!
I wonder if it's still works after doing that
Yes it actually makes the performance better due to better hear dissipation
🗨️🤖
Wow! Just this im looking for years! See what inside this SD cards!! Amazing! Thanks a lot!!
I've seen stripped connector side many times but I've never seen component side.
awesssooommeee...😸
question: what is inside a memory card?
Answer: it is memories! 😂😂😂😂
Would really like to know what laser (make / mod ) you used for this ....
What´s inside a Memory Card?
My brain instantly: Memory?!
Does work after the procedure?
Yes it actually even makes the performance better due to better heat dissipation.
@@tioswift3676 Exact, also be sure to put your finger grease on it. Also helps
Sangat menajubkan🤩🤩
The SD card standard lacks a speed negotiation protocol to tell the user the generation of the SD card.
What laser tool did you use on this?
Awesome! Good work!
Now that's cool.
Ну вот, настоящая гибридная микросхема получилась :)
that wont work now !
Fake. There's a wee little person in there writing down all your information on tiny legal pads.
