First of all could you please let us know what are you actually trying to do?
Are you developing an Android app on your desktop?
If yes, then 1 GB of RAM is almost sufficient.You might wana upgrade it...
I guess you have customised your AVD having the highest configuration.
For ex:you might be running your app in Android 4.1 version AVD.
Create another AVD with a lower configuration, you might go with 2.1 or 2.2 with lower settings.Then it will less time to load.
I too have a 1 GB of RAM, the normal apps which I have done are working well with an AVD with Android 2.2....
