Eliminates the Need for memory space Qualifiers - Silicon Labs' C8051 microcontrollers have a hierarchicalmemory structure with 6 different but overlapping memory Spaces.
Even though the hierarchical approach adds new layers of information about digitally depicted objects, it ends up saving memory because different objects can share parts.
Sequential hierarchical menus lightened the amount of memory work required of users, but forced them to laboriously navigate a maze of confusing choices and options.
