    Greetings from Russia! We have opened the Samsung I7500. We looked at the marking of the chip. Here it is: KMXME0D0CM-B601 turns out that there is 1GB RAM! What do you think about this? This decoding chip See here. Maybe RAM is disabled to save energy? In any case, very interesting! I apologize for bad English. Thanks.

    Is this some kind of fake advertizing?

    This is very strange. At Samsung I5700 and powerful CPU and more RAM, and the price he has less.

    GPP[c], would it be possible to post some pictures of your dissembled Galaxy?
    I'm surprised how no one has ever discovered this treasure lying under the cover :D

    Peace

    as my understanding,
    9. DRAM I/F & Density & Vcc& Org.
    1G (Bits) = 128MBytes.:eek:

    The RAM size spec. was in "Bits" in most case. and NAND size was "Bytes"

    Absolutely right, but then he sent this graphic with detailed data

    this is not true. theres no mobile device on the market for winmo or android that has 1gig of ram

    Don't get too exciting.
    I believed that is mis-understanding of spec. And I believe SAMAUNG did not made 8Gbits(1GBytes) DDR in one chip for market yet.
    did you remember the physical size of 1GB DDR Module used in Notebook, that's NO WAY inside this phone.

    wow, what a disappointment. I really hoped it was true, but I guess it's not.

    Yeah its in 'bits'. Remember the more ram you have the more address lines you need to reference it. That has an affect on caching and other internal structures of the CPU.

    128 = 7 bits
    256 = 8 bits
    512 = 9 bits

    Thats why usually you wont see more than 256mb on any bus. Phones with more than 256mb have some internal RAM too (internal to the CPU) on a seperate bus. Thats where these common numbers come from:

    128 + 32internal = 160mb
    128 + 64internal = 192mb
    256 + 32internal = 288mb
    256 + 64internal = 320mb

    Its unlikely you'll see more than 320mb ram in the short term unless a processor comes out with a second memory bus or more internal RAM. Its unlikely they would increase the bus width just for memory :)

    LOL, a brain fade kam? ;)
    I think it was clear the Galaxy has 192MB RAM, and after the bit/byte confussion has been cleared, I believe someone should close this thread.
    It was interesting to read though
