Dereferencing and referencing at the same time?

[Sina]

I am reading a code and I encountered the following line:

Memory *&memory;

. Seems kind of strange to me? what is the difference between that and this one:

Memory memory;

??? What is the logic behind it?

That would be a reference to a Memory* (a reference to a Memory pointer).

It's quite different from a Memory declared on the stack.

That line doesn't use reference or dereferencing at all. It's creating a reference to a pointer.
