The whole chip in general will be used in aggregate by independent vms/containers etc that do NOT read and write to the same memory. Some kernel datastructures within a given vm are still shared, ditto for within a single process, but good design minimizes that (per cpu/thread data structures, sharded locks, etc etc).
