  In this paper, employing the weak convergence method, based on a variational
representation for expected values of positive functionals of a Brownian
motion, we investigate moderate deviation %(CLT for abbreviation) for a class
of stochastic differential delay equations with small noises, where the
coefficients are allowed to be highly nonlinear growth with respect to the
variables. Moreover, we obtain the central limit theorem for stochastic
differential delay equations which the coefficients are polynomial growth with
respect to the delay variables.
