Memory usage and the differences between VM/NOVM

I'm just trying to clarify my understanding of what the differences are
between the vanilla and NOVM versions of squid and the expected memory
usage of each variant.

As I understand it the basic difference is that transient objects are
held/cached in memory for Squid/vanilla and used/written directly from/to
disk for Squid/NOVM.

However for both versions the cache index is held in memory - taking
approximately 100 bytes per entry.

The cache_mem parameter for the vanilla system configures the memory
available as a transient object store, and does not have anything to do
with the index storeage.

Are these understandings correct... or have I misunderstood the memory
usage of the 2 squids?
