Memory Pro™

Tip: Use the Stop Apps button to free memory!

Memory Pro displays the different types of memory currently available on your iPhone or iPod touch. This is different from the storage capacity used for storing music, videos or apps.

Free Memory
This memory is not being used currently

Wired Memory
This information can't be moved to disk, so it must stay in RAM. The amount depends on the applications you are using.

Active Memory
This information is currently in RAM and has recently been used.

Inactive Memory
This information has not recently been used but will remain in RAM until another application needs more memory but no free memory is available. If called upon by a process, this is quickly changed to Active memory; if it has been swapped to the hard disk, it will be moved back to RAM and marked as Active.

The iPhone and iPod touch comes with 128-512MB of runtime memory. The iPhone and iPod touch does not use the storage memory as virtual memory, so the memory available for applications is limited to the 128-512MB of runtime memory.

Apps can remain running in the background even though you have closed them.

This remaining memory can change and can affect the performance of applications, sometimes even causing the applications to close unexpectedly.

RUNNING PROCESSES
The running processes table shows all applications or system processes currently active. PID is the process ID.
