Question regarding the Internal memory of O2 XDA Exec

Hi all,
Could anyone please tell me the differences between the storage memory and the program memory? Yeah, I know this might sounds stupid and I also wish that the answer is really that straight forward.
I always thought that 'Program Memory' is suppose the memory quota for us to install application & softwares. Where, storage memory is just simply the portion of memory where we stores data that we creates.
But whenever I install applications, 'storage' is the memory which always to be used up. Yet, I can hardly use up my 'program' portion of memory...
Can anyone tell me why? and how to install applications in the program memory instead of storage memory?
Thank you very much.
Cheers!

Storage is Flash
Programs is RAM
WM5 works the same way as a desktop. It loads the OS from disk to RAM when you power it on. When you remove the battery everything is safely stored to disc, not RAM as WM2003 was. Battery can go flat, no backup battery needed.

..... so how do you save stuff to Program memory? Or is that just temp momory that stuff runs from when you execute it?

You can`t save stuff to program memory.The program memory is like the RAM in your PC,just used for temporary storage and running programs.The storage memory is like the hard drive in your PC,used for actually `storing` data.

So why do they bother displaying it on the memory settings?
And does that mean it's different to how it was on the XDA2? That used to have a slider allowing you to change the allocation for storage/program memory.

RE
I find storage memory is the one you need to watch out. As you install more programs whether to SD card or to Program memory the storage memory goes down
Too low storage memory and your system will not perform properly. Install programs with large file size first then follow by programs with smaller file size otherwise you'll encounter installation 'Not enough memory' if you do it the other way round

Should/can I move apps to storage card?

Hi
I have installed a few programs on my TD2 - all to device rather than storage card - and am getting a little concerned that performance may be suffering. With my prevous device I used SK Tools to move apps to the card - but I'm not 100% clear whether this is good practice.
With nothing running, Settings reports 223.10 MB free for storage (75.29 in use) and 75.87 MD free for programs (108 in use). I have installed things like Sprite Backup and Terminator, ActivePrint, SPB FreeCell, MyLife Organized PocketPC Edition, Resco Sudoku Touch and Gaz TD2 Tools.
Really grateful for any advice.
Thanks

I don't see why installing programs to the device memory should cause performance to suffer? It's only available RAM memory which affects performance, and this remains the same whether you instal to the device or to the card. It's when you open, and leave open, several programs at once that performance suffers.
The nice thing about modern phones is the amount of internal storage, which is plenty for masses of programs. The only performance issue you may have is when downloading large files with Internet Explorer, as I think it uses internal storage as temporary space for the file being downloaded, even if you tell it to save to the memory card. I don't think Opera does this though.
Installing programs to the card means you can't "hot-swap" it unless you're absolutely sure all the programs are closed.

In addition to the above internal phone mem is faster than mem card so performance takes a hit if you use the card.
And you run the risk of more freezes and resets being needed.
It is my firm belief that the use of internal mem avoids a lot of hassles all round by making the phone more stable.
And I almost forgot that internal mem uses less battery power than mem cards.

Easy answer...
Use removable storage for data, on-board storage for apps.
If you have too many apps for on-board storage, consider a slimmer ROM for your phone. Remember on-board storage also works as RAM for your apps, so the more you have available, the more apps you can run.

I'd check on that last statement if I were you!
The Topaz has 3 memory areas.
One for flashed ROM.
One for operating RAM.
AND one for storage.
It makes no difference how much you put in storage RAM.
It does make a difference how many apps are running at any one time in operating RAM.
A slimmer ROM image won't make much difference either.
How much of that ROM image is unnecessarily floating around in operating RAM at any one time will make a difference.
Go to settings/system/device information/hardware inforamation
I currently show
RAM size
288 MB
Flash memory size
512 MB
Storage size
342.47 MB
That's a lot of free storage available onboard that is just waiting to be used.
If you go into settings/system/memory you will find storage and program memory values displayed.
Install an app and the in use value of storage memory goes up.
Run an app and the in use value of program memory goes up.
Showing that they are two quite separate physical areas running "independantly" of each other.

Thanks!

resizing Program memory to increase Storage memory

After installing many apps in main phone memory, the Storage memory (left side on settings > memory) shrinks to less than 40MB, while plenty (and unused) Program memory is there (195MB) (right side)
Is there a way to resize these 2 main phone memories to increase efficiency?
Thanks
Saulo

I remember that in previous version on WM there was a slider to move memory from one side to another.
But this was lost here in WM 6.5.5...

are there commercial or free applications capable to do the job? Ramdisk?
It mus be working on wm 6.5.5
Thanks and waiting

what you are remembering is a time when the memory used was totally different type to what we have now.
so no is the answer, there's no way of doing it.
Uninstall some of your apps, and reinstall them to storage card, that will free up some memory, as will clearing the caches in PIE and Opera (as well as moving the cache to the storage card for opera).

Thanks Fards
Sorry to hear that...but are you aware what ihibit, prevents the memory from being resizable?
Thanks

program and system memory used to be the same memory, and you could decide how much of it was for program and how much for system. When the phone ran out of battery, it would cause a hard reset, and all your data would be lost.
Now we have a phone with two different types of memory. If your battery dies you do NOT lose your data, because the system memory is flash memory, whilst the program memory is true RAM that is cleared when you restart.
Think of your PC, you have a hard disk, and RAM, and you cannot resize the hard disk to use RAM as more hard disk space.

Yes. That's true but the main reason was that the whole thing was like RAM at these times... and we were losing everything when the battery was running out of power.
Some PDA's like HP for instance was delivered with backup batteries to prevent such complete loss and give extra time.
As from WM5.0 if my memory is good, the resident memory came up at last, to make things better.
Today, we have storage RAM which acts exactly like the hard disk of a PC and the program memory which acts exactly like the RAM of our PCs. The physical difference is the main reason that you can not slide anything between storage and RAM.
The suggestion for installing apps on SDcard can save you a big amount of storage RAM indeed. But do not forget the impact on speed: apps will load (and exit) slower on SD card. Try and see.

Yes G3K
I am loading on SD card ONLY those programs which I use rarely and in which speed is not an issue. But the more speed-demanding applications I prefer to locate on RAM, since much faster...

Memory: Storage vs Program

Here's a problem I don't understand:
How are most ppl able to install so many things on their HD2 and not use up memory space?
So my HD2 has a total of 193.43MB of Storage and 457.01MB of Program.
When I install games and programs and apps, I install them on the device. This takes up "Storage" memory.
I guess, what is the difference? And how can I choose between where (On device or micro) to install each type of game, apps, program?
1) What uses Program memory? What uses Storage memory?
2) If I install a game on the microSD, and do a flash to a new ROM, will I have to re-install the game on the microSD again?

You should keep a basic strategy:
Whatever prog belongs to the operating system (like HTCSense-hacks, GUIs etc.) or should work without storage card:
Install it to the main memory
Whatever prog is not operating system critical (games, browsers, navi-software, apps, photos, videos etc.):
Install it on the SD-Card (the setup in 99% allows You to choose between main memory and Storage Card). It will eat up little by little Your RAM (by adding values in the registry, icons regs in the startup-menu), but this might centuries ´till RAM is full.
Move Cashes to SD-card as described in
http://forum.xda-developers.com/showthread.php?t=583638
and try to keep main data memory above 50 MB.
Maybe installing progs to the SD-Card might make progs a litlle bit slower (not much though) but this way You can install hundreds of apps on Your HD2 (and never forget: before installing a new prog make a full backup of the main memory e.g. with SPB-Backup and if the new prog crashes Your device restore. Also for this it is ALWAYS better to install a new app to SD-Card instead main mem).

Program memory is RAM that is used by the operating system when executing programs.
Storage memory is where apps are installed and are then available through your icon links.
Calls are made from ROM to storage and then executed in RAM.
There are a number of issues to bear in mind when deciding where to install apps.
Installing to mem card results in slower operation of the app.
Installing to mem card results in higher power usage and therefore drains the battery quicker.
Installing to mem card can result in operating system freezes and overall slowdowns.
Installing to mem card will establish app links with the operating system that won't necessarily be usable if you flash other OS ROMs. Fresh reinstallation of apps should always be done after a flash of any new ROM anyway to keep things clean and running smoothly and reduce operational glitches to a minimum.
Any backup and restore software should only be used when restoring to the same
ROM and never across a ROM change. Sync all items you can before and resync afterwards.
Only install to mem card those apps that force you to or when you have run out of main storage and similarly have no choice.
If you know you are going to install masses of apps from the outset then as had been mentioned install operating system critical apps to main mem and the rest as you can using mem card last.
This is all good practice and good housekeeping.

Great Post !
Great thread !!!
I always wonder if Storage and program memory can be modified.
It was a long long long time ago, it was possible with my palm pilot...
Is there an application for monitoring RAM usage ?
I have about 190 Mo of free Ram and 39 Mo of free program memory.

There is no real reason to monitor any mem usage unless you operate in a memory hungry fashion. And that will only occur with the install of numerous apps. If you run out of storage mem then that's the time to do something about it and if that doesn't happen, then don't worry about it because your phone won't know the difference.

phone in low internal memory

OK guys..pardon my stupidity..i have read up on similar thread with similar situation but the thing is i do not know what is the best way to do it..i install the cleartemp but it's not working...i deleted my IE/Opera cache but i am still running on low memory..i wonder what is the best and simplest way to do it?other then hard reset thou...this phone is new to me and it's running on low memory already..my apps are install in my SD so i guess that wasn't an issue..SO! how do i free my phone memory?basically i use my phone to surf net..using IE..other then that would be youtube..need help!

And which memory because you are talking about installing apps when that has nothing directly to do with operating memory.
Installing on mem card doesn't "save" anything in this regard.

I'm also low on Storage-mem on the phone - even though I install programs on the memorycard whenever possible (and of course put my pictures, music and videos on the mem-card as well!).
I have 177mb free Program-memory on the phone but only 9.3mb storage-mem.
This makes programs such as the YouTube-app very unhappy as it seems to only be able to cache to internal storage-memory :-(
On older versions of WM you could change how the phone used it's internal memory with a slider in settings.
The phone also seemed to adjust this automatically as it became necessary.
Now however it seems that this possibility is gone (both manual and automatic adjustment).
I hope it is only my ignorance speaking so here's hoping that someone has a solution to this problem (fingers crossed)

If you have used up storage mem then that's it but what have you installed to use it.
Mine shows 152Mb storage and 252Mb program memory free. 27 apps installed and everything running fine.

Do you install a lot of application from the Marketplace? If so, this defaults to install on internal memory

I have exactly the same issue, and it's very frustrating. Pretty crazy really as I can't use the phone for anything that uses device storage. No youtube, no media busy web pages and some apps refuse to run smoothly, or at all.
Like you, I'm always having to delete Opera & IE's cache files just to keep the phone functioning! I've also deleted all my Co-Pilot files on the card and the device - this helped a little and gave me another 5 or 6 MB of device space.
With all cache's cleared and around 30 programs installed (all on the card) I now only have 7.8MB of free device storage, which disappears within a few minutes when using Opera.
Out of the 336MB of program storage I have filled 153MB with 182MB free - I wish I could control how much memory is allocated to the program memory and device memory.

Very strange...I have any large applications like games, copliot etc installed on my SD card, only small apps on my internal memory...
Total storage: 200.15MB
Used storage: 119.99MB
Free storage: 80.16MB
Total program: 336.93MB
Used program: 170.54MB
Free profram: 166.89MB

i have a 16 meg Ram Disk (see the 'ram disk' thread ) and my system temp folders and caches, plus opera cache have been moved to it. Opera now runs really fast, and the cache is no longer taking up the storage memory, plus when you soft reset it clears out the cache too.

Wow thats so confusing!
Just tell us
Storage memory (where the apps are installed)
Program memory (where the apps and OS run)
You should have plenty of mem to install ail your apps and run them without a problem.
Try installing them all to phone because you have enough mem

I have since day 1 installed all my programs to the memory card apart from a couple of programs and hotfixes which I though would be smarter if I installed to the device - but these are tiny. I have also set my marketplace to default to the memory card and removed all co-pilot files and set all podcasts to the microSD too.
Total Storage: 200.27
Used Storage: 191.48
Free Storage: 8.79 (whohooo, that's much bigger than normal!)
Total Program: 336.93
Used Program: 143.89
Free Program: 192.93
SD Card: Over 2GB's free
I really have no idea what's using all my internal storage.

Yep - that's about the same for me.
Only a few apps are installed directly on the phone (the ones that install without letting the user decide where they want them) so what's hogging my phone-storage is beyond me...
But I really don't need close to 200 mb of program-memory, is there really no way to use some of this memory for storage - as was possible with earlier versions of WM?

Have you tried importing to PC, such as pictures and other things, using Windows Mobile Centre?

I can't help but think that you've missed the point - when the storage memory is full the phone ceases to function properly!
It uses this area of storage for the cache files for the browser and for applications such as you tube. When I start the youtube app, if it opens at all, it will say 'Critically low on system memory...etc' and shut down after playing a few seconds. If I have many tabs open in opera the same memory problem occurs.
The 'Device Storage' partition is full (with what I don't know) whilst the 'Device Program' partition is almost empty. We have no control over what sizes those partitions are. Maybe i've got it all wrong but either way it's really limiting the usefulness of the phone.

yes there is. as I mentioned in post 9, I use a ram disk for my temp files and cache. lives in program memory but shows up as a (fast) memory card.
search for the ram disk thread.
also, as regards figuring out what is taking up all the space, use a file manager (don't forget to unhide all files) and search for everything over....say....1 meg.

No I haven't missed the point, I just don't get the problem and I'm trying to figure out why not?
And that would help you. Something is causing certain phones to behave this way. I use youtube and opera and never have to clear out anything.
I currently have 36 apps showing on my start menu screen and memory is showing as Storage 152.13 Mb free and program 313.80 Mb free.
I run Titanium (not manilla UI) and I have LeoLite ROM installed.
Something in that setup is causing the phone to respond differently!
