I am working on a simulation of the transmission and reflection spectra of a metal aluminum ring (conductance: 3.56E7 S/m).
The thickness of the ring is 200nm, and the substrate is silicon (epslion: 11.7, thickness: 500um)
When I set it up, I found that the running memory was so large(tens of G) that my computer couldn't emulate it.
Is there any other way to shorten the running memory and time? ?

If you are not simulating SPP effect, I would suggest you to use PEC, or better 2D sheet PEC:
Bulk metals have large permittivity with heavy loss. FDTD needs very fine mesh to resolve the physics. Therefore it needs a lot meshes so huge memory requirement.
