I am trying to wrap my head around what exactly input referred read noise is.

If you want a quantity of interest, say 'a', but only observe it as multiplied by a factor (gain), say 'G', as aG, then input referred simply means undoing (dividing by G in this case) the effect of G.

Hence, it means to get from aG (observed quantity) to an internal quantity a.
