The system uses 'near' memory model for data segments.

Proving program optimizations that are correct with respect to such a memory model.

Most modern memory models fall into one of three categories:

Yes, I know that they eventually got a nice flat memory model.

Interestingly, the latter idea was often assumed by early memory models.

So does the box not use a unified memory model?

The memory model of an architecture is strongly influenced by the word size.

An example of this is the working memory model.

A couple of studies have had results that contradict the dual-store memory model.

However, current operating systems implementing the flat memory model cannot use this capability.
