memory management unit

memory management unit
   Abbreviated MMU. The part of the processor that manages the mapping of virtual memory addresses to actual physical addresses.
   In some systems, such as those based on early Intel or Motorola processors, the MMU was a separate chip; however, in most of today's systems, the MMU is integrated into the processor itself.
