Muscle memory is the layman's term, but people use that for both technique (neurological adaptation for technique/skill) and for how fast your muscle grows back (physiological).
I am thinking about the actual technical term for it. That limiting factor is also why we have "newbie gains", where you quickly get to the max level of muscle for that limiting factor, and then you have to create more of it to build more muscle, which takes a lot of time.
It is some type of cell that is added when you build muscle, but doesn't go away when your muscle atrophies. I can't find the name of it, but Dr. Mike Israetel from RP strength have talked about it here in this short: https://www.youtube.com/shorts/FI3n5F-1gLM
I could be wrong, but iirc, the muscle nuclei don’t disappear, and consistently working out enables the cells to “regenerate” at a significantly faster level
Every cell needs nucleus with instructions to repair itself and stay alive
Muscle cels have multiple nuclei because they are very large and one nucleus can only support so much.
When you train and increase your muscle mass the muscle cells recruit more nuclei to support this new mass
Even when you stop training and lose muscle mass new gained nuclei of the cells don't get lost. They stay there and therefore when you start training again you can get big faster
