I don't agree with that.  Generally, a language specifies a virtual
machine and doesn't need to concern itself with things like "memory"
at all.  Although langauges like C tries to, look at all the undefined
behavior you get when you make assumptions about memory layout etc.

Memory representation is just an artifact of a particular
implementation of the language for a particular architecture.
