Concurrent constraint programming has been thought as providing coordination of concurrent processes on the basis of the availability and sharing of information. It classically incorporates a form of asynchronous communication via a shared store. In previous work ([1,2]), we presented a new version of the ask and tell primitives which features asynchronicity and synchronicity, our approach being based on the idea of telling new information just in the case that a concurrently running process is asking for it. In this paper we focus on a semantic study of this new framework, called Sec.The authors thank K. Apt, M. Bonsangue, A. Brogi, J.W. de Bakker, F. de Boer, E. de Vinck, M. Gabbrielli, E. Horita, J.
