"I want to manager the memory"... I kind of doubt that. The other memory should be managing itself without any help. What is it really that you are trying to do?

It does not matter if the process is parent or child. All processes are executed in their own memory spaces, isolated. Some address, say, if a variable in one process can be something different in another one, or it would not be a valid address at all. Nevertheless, for debugging and system-level purposes, one process can access memory and even control another process. In Linux, you can use ptrace:
