  The pair production of spinor particles, which can be captured by the
solution of the Dirac equation with an appropriate boundary condition, in
charged black holes is investigated. We obtain the closed form of the
production rate in the near extremal limit of the Reissner-Nordstrom black
holes. The cosmic censorship conjecture is seemingly guaranteed by the pair
production process. Moreover, the absorption cross section ratio and retarded
Green's functions of the spinor fields calculated from the gravity side match
well with those of spinor operators in the dual CFT side.
