Even though we always see the same side of the Moon, the portion lit by the Sun changes as it travels, which is why it can look full, half-lit, or barely visible at different points in the cycle. These changing views are what we call the lunar phases, and there are eight in total:

However, as a pragmatic system architect, I see no reason to eschew the MMU in favor of any of these. In fact, the MMU is composable with all of these primitives – it’s valid to have both a PMP and an MMU in the same RISC-V CPU. And, even if you’re using a CHERI-like technology for hardware-enforced bounds checking on pointers, it still doesn’t allow for transparent address space relocation. Without page-based virtual memory, each program would need to be linked to a distinct, non-overlapping region of physical address space at compile time, and you couldn’t have swap memory.
