As with any Android device, the SGH-T499 Samsung Dart has two types of memory. Put in a simple way, there is internal storage memory for applications, contacts, etc. which retains what it stores even with the phone powered down (non-volatile), and there is RAM which is used as temporary workspace for running applications while the phone is powered up (volatile). The built-in Task Manager makes it easy to monitor and manage both types.
