How can I change the ram amount that the android emulator is using?

Issue

at the first setup, Android Studio asked me that how much ram does the emulator going to use. I entered 800M but it worked slowly. I need to make it a little bit bigger like 1.5GB. How can I do that? Is it editable after the first setup?

Solution

My answer seems to be old, so for recent versions check this answer

Go to Tools->Android->AVD Manager, there's something like pencil to edit your AVD click on that, then in the pop-up window click Show Advanced Settings and there you can change the RAM size.
