I have to disagree - I ported v6 and v7 (and system III/V/etc ) - at the time we called them 'MMU's - we distinguished between a a pdp11 "base and bounds" MMU a "SUN style" SRAM based MMU (with fixed pages loaded at context switch time), a 68451 (which had power of 2 region mappings loaded at context switch time) - and full paging MMUs (vax, PMMUs, the RISC chips witrh software replacement when they came out) But we called all of these "MMUs"
