I can't find Specs/Datasheet about this "NAND" in S8500.

All I know is it has 2 GByte and maybe it is moviNAND:
http://www.samsung.com/global/busine..._MoviNAND.html

But how big is exact the RAM ? I think it is Combichip... or second Chip?
1 GByte? Or 512 MB ?

Maybe someone has the correct info found.

Thanx.

Best Regards

There are no phones with a 1 gig of RAM mate, no one is really sure, its either a 256 mb ram chip or a 512 mb chip,

Here an example... what I search for...

As I know most RAM is the half of NAND... in this case moviNAND.

Please correct me if I'm wrong.

Where did you get that idea? If the NAND was 8gb i really doubt the phone would have 4 gb of ram....

See Link in first Post... you can Download 2 PDFs...

We can see on Memory Chip in Wave S8500 and S8530:
KLM2G1DEDD-A101

1---------K---Memory
2---------L---MOVI NAND/MCP
3---------M---moviNAND
4---------2---2
5---------G---GigaByte
6---------1---NAND1 + Microcontroller----Composition
7---------D---MLC 16G Bit----------------NAND Small Classification
8---------E---3.3V(2.5~3.6)...VCC
9---------D---S3C49VDX01-----------------Controller
10--------D---5th Generation-------------Component Generation (NAND Generation)
11--------
12--------A---FBGA (Halogen-Free, Lead-Free, OSP) (12*16)-----PKG Type
13--------1---EVT1-----------------------Revision
14--------0---NONE-----------------------Speed
15--------1---Normal Sample--------------Reserved
16--------
17--------
18--------


Btw about 8GB...

I can count 3 GB SDRAM (2 + 1), but where are to see on Pics?
Quote:

The K4X1G323B, KLM8G4DEDD and K4X2G323PB represnt the 1Gb DDR SDRAM, 8Gb Managed NAND and 2Gb DDR SDRAM respectively.

If we can't find second Memory Chip... then check Service Manual + S5PC110 Manual. Both are here:
http://forum.xda-developers.com/showthread.php?t=901416

See Screenshot from S8500 SM.
1 G is marked in orange color...
Application Processor + Memory.

POP not means Prince of Persia.

Found in S5PC110 Manual...
Quote:

Package on Package (POP) option with MCP is available for small form factor applications.


If G means Giga Byte... and I think this could be 99 %. Then RAM is 1 Giga Byte.
Because 2 Processors and after Boot I think all OS + Filesystem is loaded into faster RAM... and executed from here... so maybe 512 is reserved... and the other 512 MB is organized and reserved for different things...

Just to inform you again---Galaxy S and Wave use very similar hardware, but the most important is the application core which differes slightly. However, his slight difference might not hinder in stealing things from Galaxy S firmware. The Galaxy S has got Samsung KB100000WM-A453, ARM C111A AD application core while the Wave has KAC007021M-AET7, ARM C111A AB application core.

Also, The Galaxy S has Samsung KLM8G4DEDD 8GB MLC NAND and the Wave has KLM2G1DEDD 2GB MLC NAND.

AS I KNOW THE RAM WAS 256M not 512M ,and the ram must in CPU , that's the difference ( C111A AB,C111A AD) i think

And bada is a good os , and we just need to root it
