Some embodiments provide a first interconnect circuit for accessing stored data in a reconfigurable IC. The reconfigurable IC has at least one reconfigurable circuit and a set of storage elements for storing several data sets for the particular reconfigurable circuit. The first interconnect circuit includes second, third, and fourth interconnect circuits, where the fourth interconnect circuit connects to outputs of the second and third interconnect circuits. The second and third interconnect circuits connect to the storage element sets to provide data sets to the fourth interconnect circuit, which, in turn, provides the received data to the particular reconfigurable circuit. The fourth interconnect circuit operates at a different rate than the second and third interconnect circuits. In some embodiments, the stored data sets are configuration data sets for configuring the articular reconfigurable circuit.
