The Memory panel and Watch panel come with a realtime display update function that permits you to update display of, or even rewrite, the contents of memory or watch-expressions in real time.

By enabling this realtime display update function, it is possible to display or change the values of memory or watch-expressions even while the program is running, not just when the program is halted.

For details on how to set, see section “2.11.1.4 Displaying and changing memory contents during program execution"
