How do you determine how much ram is on your iPad?

Question

I can't seem to find anything that shows how much ram my iPad has.
Also, similar to releasing or clearing cookies on my desktop, does the iPad also have this as something that needs to be cleared out occasionally?

Here is one app and there are others, mostly free, similar to it on itunes.

From an ipad forums post :
If you experience your iPad running a bit slow you probably have a ton of applications running in the background. The iPad’s memory is limited, so in order to avoid performance issues you can close background applications by following the steps below.
. To close background applications press the Home button twice and when the recently used apps bar appears, tap and hold down the app you wish to close.
You will notice that after a second or two of holding down the icon, all the icons in the recently used apps bar will begin to move from side to side. You will also notice that a small red circle with a minus sign will appear on the top-left corner of the icon. Tap the red circle to close the background applications. Once you’ve closed several applications tap on the Home button again and you will return to the Home Screen or App you were using. Your iPad should feel a little snappier.
