Is 6GB VRAM the same as 2x3GB SLI?

So, I'm trying to narrow down my budget for my new PC, and I had a question about SLI VRAM. I have an Aorus X7 Pro Gaming Laptop, and it has 2x GTX 970M, each of which is 3GB, in SLI configuration. Some people have told me SLI VRAM stacks up, essentially becoming more than each individual card, however, others have told me that's not true. SO what's the story? Does SLI VRAM stack, or is it something else?
 
Solution
It does not stack. it seems Direct X 12.1 might allow that but then only on DX12.1 cards. those 970s are effectively two 970 core s put together with 3GB of VRAM.

VRAM is just mirrored.
