I just found this picture

So does it mean only 384MB DDR is available in system?
May be this is the reason why 305M ram shows in JP3 firmware.
That could make sense.
I wonder what the difference between them is?...Could one be dedicated to the GPU or in charge of background stuff?
Did anyone notice MFC 1080p 30 fps there?
That system block diagram isn't a Samsung official one, and frankly, i think it's wrong.
If the main memory in the Galaxy S was LPDDR1, we'd see lower GPU performance, MUCH lower. Memory bandwidth is everything when it comes to GPU on mobile devices like this.

GPU RAM must be OneDRAM，OneDRAM is much faster than normal DRAM.
You can google "OneDRAM".
So I guess we might not really have 512MB of ram (as advertised)... isn't it? I mean, if these MBs are reserved to GPU use only. There will come a day when they will be needed for other use than graphics :|.
They are not reserved for GPU use only.
OneDRAM is like an intersection for routing information with as-little-as-possible blockades in the middle.
Splitting the memory to "conventional" ram and onedram is going against the very principal of onedram. I am having a hard time to believe they actually did that.

There is no official statement about RAM size.
I noticed the diagram says "TFT LCDC". That seems wrong, does it not?

This. You'll find a lot of press about the Galaxy S having 512mb RAM, but where does Samsung itself advertise this? I cannot find anything about it anywhere on Samsungs website. Maybe we should ask them?
GSMarena pressed on the issue when the phone was released, and samsung replied that there are indeed 512MB.
Lol....So do we actually know if it has 512MB of RAM or not? As some others have stated it might help explain why the Sammy has lag issues and the Desire does not..
BTW, I dont own either at present and am just going by what I have read in these forums.
That diagram also doesn't list wireless N, does that mean our phones don't have wireless n???

well..... using my onboard math processor I compuete that 384+128 = 512..
So samsung wouldnt have been lying if they had said there was 512.. even if 128 might be dedicated to the gpu or something else. 512+128 would have been nicer though.
I wonder if this diagram is accurate.
The picture is of ODROID-T which is a tablet style device for developers.
Its hardwares are quite similar to SGS but I don't think this block diagram should be showing exactly the same informations as SGS's.
Have a look at this site;
http://dev.odroid.com/wiki/odroid-t/
Well, the S5PC110 doesn't have the memory built in beforehand. It's changeable, the controller supports OneDRAM, LPDDR1 and LPDDR2. You can stick whatever you want in there.
Remember that only what's in the blue square is the actual SOC.

How does this differ from the HTC Desire setup? I know it has 576 MB RAM, but not sure how its split up...
Well, I checked before posting. Google for an official press release from Samsung Australia. Xda is not letting me post external links due to my low number of posts. However, I love my S. I'm just saying that this mem thing is starting to smell a little bit of i7500, from a customer relations' POV. Let's just hope we actually have a different design and that, as rumors say, new kernels will unlock all available ram.

I also found a tear down analysis of Korean version galaxy s.
The author said it has "4Gb NAND+3Gb DDR+1Gb OneNand",which is incorrect.
Some comment below said it is OneDram actually.
If not for the OneDram,How can samsung declare 90M triangles/sec instead of powerVR's figure of 28M triangles/sec.
OneDram is more expensive than DDR.
I guess samsung does't say anything about RAM because it's a different structure,and hard to explain.
gosh i have been lurking on these forums to buy this phone
but with this memory issue it seems like the OMNIA II all over again
there the phone was advertisied with 512mb but only so little was left to the user!!
samsung samsng oh samsung!
Owning both devices (JPO on Galaxy S and JJ7 on Tab), I wonder about the huge difference in available RAM. Both have 512mb built-in with the Tab having about 430+ available but the Galaxy S only having 304mb. Now my tab runs wifi only but even plugging in a SIM does not make much difference to the available RAM.
Anybody having a good explanation for this?
Tab really has more physical ram. There's 128mb more in tab. Why this is not reported in spec sheet, I don't know.

Galaxy Tab 10.1 32GB (model GT-P7510)
Honeycomb 3.1 (build HMJ37.UEKF3)
purchased open box retail at local bestbuy
was unlocked when purchased
works fine
encrypted. set up. installed about a dozen apps.
storage space seems fine:
28.01 GB available - 433MB of apps - 133MB of files - 4kb fluff = 27.46GB available
however, internal memory seems busted:
Settings/Applicaitons/Running reports 171MB used and 407MB free
?407
* What do you other GT 10.1 owners show?
* Should this be a real 1024MB available?
-----------------
Over in the GT General forum, it was suggested that the memory is in use by the graphics card. It seems a bit high for the GPU to reserve 500+ MB for 12x8 scrreen, especially w/o any 3D running.
* Does anyone have data on how the Tegra 2 SOC deploys memory?
------------------
basically, I am trying to find out if I have a defective/tampered unit or not.
My galaxy tab has total RAM of 723. I know the Iconia has 724. I believe all Tegra 2 based devices are around this range give or take some compiled kernel parameters tweaked allocation ranges. You dont have a defective tab....
Its a somewhat complex topic and reserved RAM for the Geforce ULP is just a part of the amount allocated. A good google search should yeld alot of results with the same questions and answers and more details.
Hello everyone,
Samsung is releasing DUAL SIM card phone Galaxy S Duos phone (S7562).
Specs:
Additionally, the phone has Android 4.0, 1GHz CPU, 512MB RAM, 3G, 4-inch 800×480 display, 5 megapixel camera, Wi-Fi, GPS, microSD card slot and 1500mAh battery.
The same specs as our SGS have. With only 512 RAM and it will be ICS out of the box.
So our SGS capable of running Touchwized ICS.
http://www.sammobile.com/2012/07/30/samsung-to-launch-dual-sim-galaxy-s-duos/
The I9000 (SGS Amoled with Samsung SoC) is advertised as 512Mb Smartphone, like the I9003 (SGS LCD with Texas Instrument SoC) also. The I9000 have physically 512Mb RAM in the SoC, the 9003 have 640Mb, and you can see this difference between Stock Samsung ROM in 2.3.6 and the 128 Mb make a difference with LMK usage. End of story.

Does i9003 getting official ICS? If not, than samsung is lying about the i9003
Samsung doesn't care about customers on long term stages the only interesed that you buy new deveices every year.Apple is much better at this stage they care about it that their devices are updated and users satisfided.
So If you don't like apple you can buy nexus device this device is also up to date.

Sales of i9003 are very different of i9000. And people who doesn't care to have a 9003 (SLCD, less powerful GPU, etc. etc. than i9000) mainly doesn't care to have Android 4.x instead of 2.3.x because their smartphone WORKS in 2.3.x. If you want a bleeding edge smartphone, go with the Nexus line, not a consumer line. Period.

Yes yes we all know but we can`t do anything about it
Has more RAM than Galaxy S. They were both advertised as 512 MB but Galaxy S had 512 physical memory while Duo probably has 640 MB physical. Think i9000 and i9003.

That is true for high RAM devices like Galaxy S II, as there is still plenty of RAM left, but 128 MB is actually a significant difference for low RAM devices like ours. The HTC Desire with 576 MB RAM (64 MB more than Galaxy S) couldn't even get a proper Gingerbread update due to RAM shortages as they had to fit Sense in. Imagine Galaxy S with 4.0 and Touchwiz? It's "impossible", by that I mean you won't even be able to multitask and run the device properly with all that Samsung bloat on top of it.
Galaxy S would run an AOSP properly because it is nowhere near as bloated as Touchwiz but no manufacturer (except google) has released such an update.
Also, keep in mind the issues we just ran into with our phones' jellybean update. The faster NAND on the device is limited; I guess this is just bad foresight on samsung's part. Raw ICS/Jellybean was already too big to fit onto the NAND. Put in Touchwiz apps and customizations and you need a much bigger NAND to fit it all in.
