Does anybody know what kind of memory chipset this phone has? What is the bandwith and speed of ram memory?
Medfield SoC come with a dual-channel LPDDR2 memory interface:

So that what it should be on the Razr i.

Is there/will there be any way to get more than 4GB storage?
Does the phone have USB host support to connect an USB stick?
Is there any Bluetooth/Wi-fi flash reader or USB hub on the market?
Hmm, not sure if it has host support, but wouldnt a usb stick just defeat the whole purpose of having such a small device?
It might be possible to use bluetooth to connect to a flash reader etc, but i don't think windows would have native support for that.
The only other way is to open it and replach the flash chips - but that depends on what package chips they use and what lines they run on the pcb. I'm quetly hopefull.
no it doesnt allow for extra storage to be put on, unless your into NAND stacking...

i don't know how much truth is there to this but check this out:

"GPS enabled HTC Diamond’s specs are all over the internets and we thought we’d share this with our readers:

256MB ROM / 128MB RAM
7.2MB HSDPA / HSUPA (rev A EVDO for Sprint versions)
2.8″ VGA screen
WiFi
Bluetooth 2.0 with EDR

900mAh battery

hmm and i don't think they are right ..
the HTC DIAMOND DOES NOT HAVE A MICROSD SLOT!!!
These are olddd specs from end april. I think its safe to say its conclusive there is NO memory expansion slot on the diamond.
I don't think it's correct either. The Diamond has the 4GB internal and no expansion, the Raphael has the qwerty and micro SD expansion and no internal 4GB. Unless they have changed it. Thanks, JASTECH

tHIS IS JUST A Random testsdlkcvnlkcvsd.;mldv;dv2v465sdva5
I just got an idea of running some old games on my TD2, but some of them require reading from CD.. That's ofcourse possible only through SD card as internal memory isn't big enough. But I couldn't find any disc emulator for windows mobile so I got 3 questions:
Is it possible and is there something, that could do the job?
If even it would exist, is 8GB class 4 SD card fast enough to support even slow 4x CD rom reading speed?
What performance hit could emulation cause? Eat whole CPU? Most of the games are for 486(arround 100MHz) and can be run in DOSbox, but that's the next layer of emulation so it may not be even worth of an effort

Hey guys,
I've been looking over this document: SD 3.01 Spec specifically from pages 13-15 regarding UHS modes. It would appear that in order for the host to access the card at UHS DDR50 mode, it simply needs to issue another command after initialization. My questions here are:
1) What is the SD host controller on the Nexus One (i.e: is it part of the Snapdragon QSD8250 SoC, or is it a separate chip that it contacts over a serial bus?)
2) Can portions of the AOSP/Kernel/Reverse engineered host controller firmware be rewritten to support UHS-I speeds, or is this impossible in a host chip designed before the SD 3.0 spec was even released?
Thanks in advance.
SD controller is a part of QSD8250.
To access the card, you need to send the command. To receive the card's answer and any communications afterwards, you need HW logic to sample and further process DDR communication. If this logic was present - this thread wouldn't be open...
Aww, was hoping maybe Qualcomm future-proofed the QSD8250 a little bit. Oh well, thanks.
In may of last year, AMD made announcement of their entrance into the ARM microprocessor line, and the hybridization of ARM and X86.
Long before this, I had wondered if it would be possible for a computer to operate on a hybrid architecture. To task a certain amount of its work to a powerful CISC type processor as well as add a super energy efficient RISC chip to handle co-processing .
This type of heterogeneous computing is being done already with ARM processors using 2 different architectures. However, the two are similar enough that they are assembly code compatible. The ARM big.LITTLE architecture is close to what I am talking about, but still both are ARM v7 processors so not really an ISA hybrid?
I'm talking about an ultra low power, hybrid architecture mobile phone, running an OS like Android, that uses an Intel / AMD x64 processor as its main CPU. With a similarly powerful ARM coprocessor.
A CPU with the performance and compatibility of a desktop PC. More instructions per second at a lower clock, fewer cores equal to the same computing in equivalent ARM chips.
Better software compatibility. No more writing custom kernels for custom chipset. No more blank won't run on blank because of the chipset.
And at the same time, by adding a coprocessor by ARM, an enormous amount of resources can be offloaded to the copro, which means less power consumption, less heat generated etc.
Say your phone had two chips.
One containing a very powerful x86 system with CPU, GPU, SDRAM interface etc. The main " north bridge ".
And a second chip or " south bridge " containing an ARM processor, cellular baseband, DSP , audio, video etc etc.
The south bridge could work independently of the north, allowing for tasks like making calls or processing multimedia to be done on its own CPU; leaving the application tasks strictly to a bad ass 64 bit Intel processor that could run full on i386 Linux or Windows?
Great.maybe the future of Mobile Computing devices
