We propose the two-leg fermion-ladder models for SU(2|2) and SU(4) cases. The
former is exactly the extended Hubbard model proposed by Essler, Korepin and
Schoutens. The later is a new model also with $\eta$-pairing symmetry which is
important for superconductivity. This new extension of the Hubbard model can be
solved exactly.
