Is it possible to upgrade the PS Vita's ram?

Solution
No. The RAM modules are attached to the motherboard and not replaceable. Even if you did, it isn't designed to use more than what it has and wouldn't make any difference.


Found out Vita's memory sticks are specifically made to supply a dependent amount of shared memory for the CPU. That's why they're sooo expensive.

In easier words, Vita's memory sticks give Vita's GPU more ram.Vita's GPU is like a integrated GPU on a laptop.

You can tell me that'snot true, BUT try opening up 10 programs at once on a 4GB memory stick and then 64GB memory stick ad then come back tell me the difference. I realized there is no need for this upgrade at all.
 
I don't think you understood what I meant. With consoles like the PSVita, the PS3/PS4, Xbox360/XboxOne, there are no ''ram stick'', the memory modules are stuck to the motherboard and you can't replace/upgrade them. It's not like a regular PC, where you have a slot on the motherboard that can accommodate different RAM configurations, depending on your needs.

Of course you can run more apps on 16GB of ram on a PC than if you had 4GB, because the software on the computer will allow more apps to be opened when more RAM is available, up to a certain limit. The same is not true for a console. Their software is optimized to only use what is available to the console, so it wouldn't allocate more than what it comes with, even if the memory was available.
