That isn't necessarily the case. You can have memory protection without a MMU - for instance, most ARM Cortex-M parts have a MPU which can be used to restrict a thread's access to memory ranges or to hardware. What it doesn't get you is memory remapping, which is necessary for features like virtual memory.
