As we know LGP500 has 512MB of ram and GT540 has 256MB. I've just looked to service manuals to compare and make sure that it's 100% other chip with more memory. What I've seen ?
Phones are using multi chip package (RAM+NAND memory).
But most interesting is this:
GT540 uses
K524G2GACB-A050 chip produced by Samsung. This chip has 4Gb(256Mx16)NAND Flash Memory&2Gb(64Mx32)DDR SDRAM
LGP500 uses
MT29C4G96MAZAPCJA-
5ITFBGA chip produced by Micron. This chip has also 4Gb NAND Flash and 2Gb DDR SDRAM
Pins of this chips are totaly same. Only diffrence is that GT540 doesn't uses 2nd layer (2 pins called CS1 and DCLK1
But anyway I want to ask where is that 4Gb NAND and 2Gb RAM ?????
Lol you are tryng to say our phone as 2gb of ram and 4gb nand?

As we know that p500 is armv6 phone. Maybe the processor and system architecture is not capable of addressing 2gb of ram...
I compare this numbers 4,2,512,256 and guess what:
1st : Gb means GIGABITS
so :
4Gb NAND Flash is phone memory used by data system etc and 4096/8=512MB of memory ;] (used also by kernel etc so thats why you don't have 512MB)
2Gb DDR SDRAM is RAM and 2048/8=256MB of RAM.
Thats all.
LGP500 using 2nd generation of this memory and it have 4Gb NAND and 4Gb of RAM
MSM7227 can work with 1GB ram but chip must use more addres pins, not more data pins.

Hi, I have one question. Optimus 3D has a Dual-Memory, so it means that he has 2x512mB RAM ?
No.
Some more info:
http://en.wikipedia.org/wiki/Dual-channel_architecture
it will have DDR2 memory, as opposed to the other phone currently and being released only have DDR memory...
basically in easymode jargon the memory is faster
I read that it has 4GB DDR2 RAM.
I'll try to find the website I found it and post it here.
EDIT: It has 4Gigabits of RAM not 4Gigabytes. So in reality it has 512MB of DDR2 RAM.
Its probably an LG marketing "scheme"? Lol

Probably a dumb question but I did not find anything in searching. It says that the Xoom uses DDR2 Ram. Can this be upgraded to 2gb with a different DDR2 Ram module?
No.

Just like phones ram is built into the board.
It will be amazing in the future if we have upgradable devices.
But for now, no
The EVO 3D is basically the same phone as the Sensation with the addition of 3 extra Gb of RAM. The spec sheet for the Sensation on HTCs site lists 4Gb of RAM with a note that only 1Gb is user accessible.
Internal Memory
768 MB RAM, 4 GB Internal Storage (1 GB user addressable)

I remember when T-Mobile's version of the HD2 came out and it had 768 Mb of RAM vs the 512 in the European HD2s and there was a way to unlock the remainder of the RAM with a hack for the Euro models.
I'm sure given HTCs track record that they've used the same hardware (makes sense) to cut down on costs so it's just a matter of a hack from the community to unlock the remaining 3Gb of RAM.
What say ye?

I guess you mean ROM and not RAM...and I've read that it is not possible...
Sure just buy a couple of DDR3 sticks and jam 'em in the microSD slot.

No, said RAM, meant RAM....
You can do the research, I was going by memory but it actually had 1Gb of RAM vs the 448 in standard HD2s. The Euro HD2s had an unlock that at least gave them 576 Mb, I'm guessing the same will be true here.

As you said in your first post, the Sensation is listed with 768 MB RAM, 4 GB Internal Storage (1 GB user addressable). Some of the 768 is then used for Android and Sense, with the remainder being open to run other applications. The 4 GB with 1 GB user addressable is NOT RAM. RAM is volatile (non-permanent) memory that is VERY fast and used to store the data for a currently running process. The user addressable space is non-volatile and is used for permanent storage of applications, contacts, photos, etc. It is not possible to use this as RAM as it is flash memory instead of using capacitors like the RAM found in cell phones (which provides the speed needed).
Some of the remaining 3 GB might be open in the future after the bootloader is unlocked and custom ROMs are flashed as they would be less memory intrusive than Sense. This might also free up some extra RAM from system use, but there is no possible way to increase it beyond 768 - whatever vanilla android requires to run.
Hello All,
I have started this thread as I couldn't find relevant info anywhere else. I purchased a Galaxy R 2 days back. As mentioned in the specifications on the box, the device has 1gb RAM and 8 gb internal storage along with 2gb ROM. However, when I check my device, it shows only 768 MB of RAM. Again internal storage shows to be only 3.75 GB and not 8 GB. Please comment.
If a similar thread exists, please merge, I couldn't find one.

yep I don't know how it should be (of cours beside RAM becouse its ok) but I have just like you in mine...
yep same like mine also..
8gb internal storage and u'll get 3.75gb..
if u wanna check again.. try it on SGSII 16gb.. only 12gb is usable for user..
so meaning almost 4gb of storage will be used up by android or samsung touchwiz? not sure though.. maybe some1 can explain better than me.
and the ram also the same. hope this help!
A lot of space is reserved/used by Android. You do not see it because an unrooted device does not have access to that area. Buy a cheap 32 gb sd card.
I think mrsaccess won't be mad if I link his post, where he explains that in a great, simple way.

The SAMSUNG Specs for HK is User Memory: 8GB (ROM: 512MB ; RAM: 1GB)
The user memory includes RAM and ROM as well.
Internal USB Storage 3.75GB+ Internal Device Storage 1.5 GB+ RAM 1 GB. max (256 MB for GPU)+ ROM 512MB Usable (Max 2GB)
Can it be like above case? I saw some reviews and posts around the web saying like this. I am not sure, and someone can give more deep insights.

I don't think so.
Galaxy R specifications:
- 1GB of RAM (256MB for the GPU, 768MB are free).
- 8GB of internal storage (2GB ROM, 2GB for applications and 4GB as mass storage).

I assure you that everybody does!
I would like to know is there any way to Fake ram size like which is in Settings/apps/running.....my friends are using 2GB ram device & I am using 1GB ram device...So is there any way to change the 1GB ram to make it look like 3GB..etc
I saw so many clone/replica android devices showing Fake Ram sizes..even antutu benchmark can't recognize Fake ram info....how to do it...??I have rooted and i know basics to edit xml files,decompile, recompile...Please help
IDK why you want to do it but here you go. Press thanks if you like it.

It's just a game but what I wanted was something like changing the system wide Ram to a fake value ram...like 1GB ram to 4GB ram.....there are many Samsung replica/clone which show 2GB Ram but true ram is 512MB....how do they do it....I need to do it like that....any help guys...??
