Based on the work of Majhi et al., we investigate the entropy correction to the Kerr-Newman black hole beyond semiclassical approximation by the Dirac equation. Because in the units G=c=kB=1,the Planck constant is proportional to the square of Planck Length,Planck Mass and Planck Charge,the proportionality parameter of quantum correction terms to the semiclassical term of action is taken as (Mrh-Q2/2)-1. With the aid of the differential form of horizon equation and the first law of black hole thermodynamics,we obtain the corrected entropy of charged stationary black hole and find that the correction terms also include the logarithmic and inverse terms to Bekenstein-Hawking entropy.
