2. Said of a memory architecture like that of the vax or motorola 680x0 that is one big linear address space (typically with each possible value of a processor register corresponding to a unique address). This is a good thing. The opposite is a "segmented" architecture like that of the intel 80x86 in which addresses are composed from a base-register/offset pair. Segmented designs are generally considered cretinous.
