what do u call the memory of the tanager that is 8mb without the MMC or SD card? is it really the same with the canary's?..........sorry if my question sounds stupid. thanks much!

As far as I know the SPV (Canary) and Tanager are identical from a memory point of view.

I presume you are referring to the IPSM folder - this is the read/write part of the phone's internal memory, used for storing applications, ringtones, homescreens etc. The IPSM is 7.5MB in size, so I presume this (rounded up) is the 8MB you are referring to? ;)

yes,dude.that's what i was reffering to. what does IPSM stand for? what is the difference between the ROM and the RAM?

IPSM = Intel Personal Storage Manager (or something similar).

The Canary and Tanager handset have identical internal specifications. The ROM is "read only", and, in general, is where you install permanent files such as applications, videos, documents, etc. It also holds the Windows CE files, which are mostly in Windows and the rest in IPSMWindows. However this space is limited and ideally you would install the majority of your applications onto a storage card.

RAM is the run-time storage. All applications use this as it would be used in a normal PC, for calculations regarding the applications processes. The more RAM you have, the more applications you can run, they will also be more responsive. If you have larger amounts of ROM, you will be able to install more applications and copy more files directly to the phone.

IPSM = Internal Persistent Storage Memory

Data stored in the RAM is only there until you switch the phone off. Once you switch the phone off, the RAM is wiped. This is the memory used by the OS and other applications while they are running.

Data stored in the ROM will survive when the phone is switched on/off. This is split into two sections. One holds the Operating System and you cannot normally alter this. The other part of the ROM is the IPSM, which you can access and write to.

Hope this clears things up a little! ;)

Hehe

NB:

Intel Persistent Storage Manager (IPSM)

I knew Intel was in there somewhere ;)

RAM - Random Access Memory

ROM - Read Only Memory

Well said madukrainian. The kids of today just want to get involved and don't read the things called books ;) Easy explanation is that the contents of a RAM chip can be changed, contents on ROM cannot.

A ROM chip is set like it is forever and can never change. Technology has advanced to the point where RAM acts a little like ROM in that data is retained even when the power is turned off, but it's still RAM. If you can change the contents of the chip, no matter how, then it's RAM.

How many times have you flashed a CMOS chip, for example?

Ah, that's my point. Flash is RAM, not ROM. ROM cannot be changed at all, ever. RAM can come in a variety of forms and some (such as BIOS) are read only 99% of the time, but can be amended under certain conditions. It's still RAM, just over the past 10 years or so the RAM has merged more into the domains of ROM.

I doubt it's of as much importance these days as it was when I was at school learning all this crap

OK, point taken ;)

And yeah, it is knda irrelevent nowadays....

My tuppence worth:

Another point with BIOS / CMOS; it needs an electrical charge to retain it's contents (thats why you have a BIOS battery on the motherboard), another reason for it to be defined as RAM.

Another thing to throw in (and going more OT by the second :wink: ):

EPROM - Eraseable Programable Read Only Memory. This type of Read Only memory can be changed and doesn't need an electrical charge to retain it's contents. A lot more hassle than just using a battery though!

guys,correct me if i'm wrong.let's say,i'm not using a memory card.i used up all the 7.5mb IPSM with applications.if i open up 2 or more applications,will the exact size of the application go to the RAM of the tanager?

Not nessacarily. It depends on what the application is doing, storing, calculating etc..

u mean,its not advisable to fill up the 7.5mb of applications?

This has confused me in the past.

The Tanager/Canary has 32meg of memory, which is a 16/16 split between ROM (install space) and RAM (runtime space). Now the Windows CE image alone takes up over half the ROM space, leaving 7.5meg left for you to install applications onto. However, you are advised to keep the memory at least half empty. Is this the total 32meg memory (which you cant install past the 16meg mark anyway), or half the ROM space (which is already taken up by Windows)?

Presumably, you can fill the 7.5meg with no side effects, and there will still be the 16meg RAM available for applications to use when running.

Either way, i install all my applications onto my SD card for the sake of tidiness, but i would say its ok to fill the 7.5meg internal storage with no problems.

Hope that makes sence, had a little thinking out loud then ;)

you cleared everything up.dude,thanks a million.

Having just said that, according to this page its 16/32 RAM/ROM.

So i give up, if someone does know how its split up please let me know! (maybe CE takes more space than i thought? ~shrug~)
