It probably has more to do with some type of corrupt app data that is stored on your iPad. You obviously have a lot of stuff on your device and if you play games - there could be corrupt data in one of those games. It could be a corrupt photo somewhere - or a hinky graphic in a document.
The standard fix to find a corrupt app is to delete all of them from the iPad - deselect them in iTunes and sync. Then start syncing them back onto the iPad a few at a time. Work with the iPad with those apps for a while and if you have no freezing issues - sync a few more back onto the iPad. Keep repeating the process until you find the app that is causing the problem.
You could also have too much going on in the background so you could try quitting a bunch of open apps via the mutlitasking tray at the bottom of the iPad.
Finally you could try a hard reset to see if that helps. Try a hard reset by pressing and holding down on the sleep button while holding down on the home button at the same time for about 10 seconds, until the Apple logo appears - ignore the red slider - and let go of the buttons.
