It is well-known that wave-type equations with memory, under appropriateassumptions on the memory kernel, are uniformly exponentially stable. On theother hand, time delay effects may destroy this behavior. Here, we consider thestabilization problem for second-order evolution equations with memory andintermittent delay feedback. We show that, under suitable assumptions involvingthe delay feedback coefficient and the memory kernel, asymptotic or exponentialstability are still preserved. In particular, asymptotic stability isguaranteed if the delay feedback coefficient belongs to $L^1(0;+\infty)$ andthe time intervals where the delay feedback is off are sufficiently large.
