That's based on C. elegans which I think that only has 902 neurons. Also I don't think they've ever cloned the state of a living worm, only the connectome. That itself is pretty cool but it seems like what Samsung is talking about would go pretty far beyond that.

Even simpler at 302 for adults, their nervous system is completely mapped out and I'm still incredibly impressed nonetheless by how much technology has progressed in my lifetime to make something like that possible

They embodied the brain in a basic truck type robot, and it's oddly awesome.

Since worms usually survive electric shocks (and people usually survive seizures), the connectome is probably enough; there probably isn't anything vital in volatile memory. Less-volatile memory like DNA methylation has been proposed to be a significant memory mechanism at the per-cell level but so far, as I understand it, there is not good evidence for this.
