Need to know what these figures mean, as regards RAM on my SE

[Guest glossywhite]

Hi there. So I put my phone into

./adb shell

and then ran

cat /proc/meminfo

which returns:

$ cat /proc/meminfo

My question is, this Sony Ericsson "Live with Walkman" (wt19i) is supposed to have 512Mb ram on the specs... so how much does it actually have?

Thanks

it has 512MB RAM, hackbod explains it best here: https://groups.google.com/group/android-platform/browse_thread/thread/adb2fa9946275b73

That is the amount of RAM available to the system. RAM is used for other

things like the frame buffer, window surfaces, etc.
