The standard Josephson junction is the tunneling between two superconductors.

Intrinsic Josephson junction is the tunneling between two layers that are part of the crystal itself. In the cuprate superconductors, this is the tunneling between adjacent CuO layers for compounds having more than a single CuO layer in its structure, such as Bi-2212, which has two CuO layers per unit cell. It is believe that all the charge transport occurs in the CuO layers, so this should be where the supercurrent resides.
