The HTC Alpine is a faster Himalaya with a better camera (but the pictures are the ugliest ever seen) and with Wi-Fi support. The device contains a 64Mb ROM, and a 64MB DiskOnChip, and 128Mb RAM. The rom contains the OS, Extended ROM, BootSplash and some Serial Numbers. The DiskOnChip contains the Storage directory.

Is the rom size of xda2 64mb and ram of 128mb?
My device information/hardware shows 128mb of ram and ony 32mb of flah size.
Why is that happen? I thought is a 64 rom machine...
thanks
For my prophet, in memory, the total memory only 96.XXMB(including program & storage). Then, including there are 5XMB ROM installed in machine and about 10MB ext-rom. there are only about 150MB...How come 190MB(128+64MB)???
What does ROM and RAM means related to the HTC TyTn ?
HTC TyTn ROM = 128 MB
HTC TyTn RAM = 64 MB
When you install application to the "Storage Memory", where will it be installed ? in the RAM ?
What are installed in the ROM ?
Where the default application from the provider (e.g. T-Mobile) are installed ?
Thanks!

The 128 MB of Flash ROM is broken into two parts:
- 64 MB for "Storage" (think hard disk space)
- 64 MB for "Program" execution (also called "RAM")
Programs reside in storage until they are activated (at which point they are also loaded into RAM). The amount of RAM you have available is what's left after loading the OS.
The carrier apps are also stored in ROM/RAM.
RAM is used to run applications. Its content gets lost on power off.
ROM (Flash RAM indeed) is used to store firmware, to install user applications and to keep data. Its content is kept even without power. "Extended ROM" is also a part of 128MB "ROM".
As I understand, HTC TyTN has NAND flash, and so no XIP and PagePool consumes a lot of RAM, though making things to run faster.
A good reading for beginners is here and here.
I don't like the tendency to call flash memory that is writeable as "ROM" (=Read-Only Memory). IMHO it provides a lot of confusions.
Very good explanation Lurker0, and both articles are worth reading for anyone!
HI!
I have a Orange SPV M600 and I'm wondering why there is only 44MB of ram showed in memory aplet, but when i look at the product information there is shown 64MB, same goes for storage memory in product information it says there is 128MB but in memory aplet it says only 42MB.
Thanks for all the information.
Well, first of 64 MB on the package is always less on the system, just like with hard drives.
It is in fact around 61.3 MB because in real life MB is not 1000KB but 1024 and KB is not 1000 BYTES but 1024.
Then there is the part taken up by the system when its running .
As for storage, keep in mind that half of it is taken up by the ROM (the OS) plus 10MB is taken up by your extended ROM. (Which you can reclaim if you search for the reg settings in the WiKi)

what does mean UNLOECK AND USED FOR STORAGE in ur tagline?
prob means that he removed it to use it for storage space, the way he described to you...
Extended ROM is hidden by default and used by Cell companies to store their customization installation.
In my case (imate ROM) it contains Backgummon, eTrust and old Skype version.
Using reg settings found in the WiKi the ext ROM can be shown and the files can be removed / added through the file manager.
I use it for some stuff I do not want in main storage but can't put on SD.
where can i download the orange mpv600 rom?
i wanna try.
I've upgraded to Tomal 8.5 and now have the following stats on my home screen:
RAM : 24MB
ROM : 38MB
ExtROM : 10MB
Flash: 12MB
I used to have tomal 8.2 so am used to the flash disk and can see that ExtROM maps to a device named "Storage" but what is "ROM" for, is that free space i can use? This also adds to my confusion over Storage vs Program memory, it looks like ROM = "Storage Memory" and RAM = "Program Memory". Also when you install things it asks you if you want to install to the device or flash / sd card etc. Is "Device" ROM or RAM or some mysterious merging of the two?
ARGH!
What is all this stuff? Basically, where (pending my new 4GB SD Card arriving) should i install stuff? where should i save photos from the camera? Is some of it volatile and some of it non volatile? is ExtROM slooow and Flash fast? This is all a bit freaky
It's amazing what you can find in the wiki. There's tons of interesting answers to loads of questions. There's even a section called Memory Storage Types.
ok, i swear that page wasn't there an hour ago thank you
