I had a program under OS 9 that could be used to do this (mostly to cheat at games :) That programs usually didn't dare to just write and used undocumented APIs from PrivateInterfaceLib instead. Most modern operating systems do not allow one application to access memory of another application (apart from shared memory which requires the processes to cooperate). Well, most modern OSes allow you to do it through the VM APIs and you can map a portion of one process's virtual address space into your own process's address space where you can change it and possibly write it back if you have the enough privileges to do so, of course.
