Whilst all the choices you make tend to be in the grey matter, the rest of you does have internal state - mostly in your white matter.

Yeah, but so? Does the substrate of the memory ...matter? (pun intended)

When I wrote memory above it could refer to all the state we keep, regardless if it's gray matter, white matter, the gut "second brain", etc.

Human brains are not computers. There is no "memory" separate from the "processor". Your hippocampus is not the tape for a Turing machine. Everything about biology is complex, messy and analogue. The complexity is fractal: every neuron in your brain is different from every other one, there's further variation within individual neurons, and likely differential expression at the protein level.

As the article above attempts to show, there's no loop. Memory and state isn't static. You are always processing, evolving.

That's part of why organizational complexity is one of the underpinnings for consciousness. Because who you are is a constant evolution.
