In computer science, a single address space operating system (or SASOS) is an operating system that provides only one globally shared address space for all processes. In a single address space operating system, numerically identical (virtual memory) logical addresses in different processes all refer to exactly the same byte of data. SASOS projects include the following:

has abstract	En computación, "single address space operating system" (SASOS) es un tipo de sistema operativo con un manejo simple de memoria que utiliza solamente un espacio de dirección virtual. (es) In computer science, a single address space operating system (or SASOS) is an operating system that provides only one globally shared address space for all processes. In a single address space operating system, numerically identical (virtual memory) logical addresses in different processes all refer to exactly the same byte of data. Single address-space operating systems offer certain advantages. In a traditional OS with private per-process address space, memory protection is based on address space boundaries ("address space isolation"). Single address-space operating systems use a different approach for memory protection that is just as strong. One advantage is that the same virtual-to-physical map page table can be used with every process (and in some SASOS, the kernel as well). This makes context switches on a SASOS faster than on operating systems that must change the page table and flush the TLB caches on every context switch. SASOS projects include the following: * Amiga family – AmigaOS, AROS and MorphOS * Angel * BareMetal * Br1X * Genera by Symbolics * IBM i (formerly called OS/400) * Iguana at NICTA, Australia * JX a research Java OS * IncludeOS * Mungi at NICTA, Australia * Nemesis * Opal * OS-9 * Phantom OS * Scout * Singularity * Sombrero * TempleOS * Theseus OS * Torsion * VxWorks * Zephyr (en)
