HP PRIME - Available Memory / Memory in use ...

[cyrille de brébisson]

Hello,

No, that is a little bit more complicated than that.

Flash storage is used for permanent storage and is 256MB.
Out of that a portion is reserved by the OS for itself, future updates and buffers (all together around 64MB). This leaves ~ 190MB for the user.

All your data is saved there, lists, matrices, programs, comments, apps....

RAM is 32MB
But, as stated, the Flash is only storage, it is not possible to work from flash, so the OS has to load itself completely in RAM to execute. This takes around 20MB.
Then the OS has to 'work' to do that, it also needs RAM. For the screen, various buffers, datastructures, flash cache (for file access...)... This takes an additional 4MB...

This leaves a total of 8MB of 'free' ram.
When a user program, list, matrice is used, it is loaded in RAM. It is not loaded unless it is needed. so you can have more user data in flash than there is RAM available in the same way that you can have more user files on your computer HD than you have RAM on your computer.
