A routing device and associated method for allocating the nodes of a multi-way trie of a forwarding routing table between two or more memory devices is disclosed. In the preferred embodiment, the routing device comprises a routing table for storing a plurality of routes in a multiway trie in a first memory for caching a first set of the plurality of trie nodes and a second memory for caching a second set of the plurality of trie nodes; and a route manager adapted to relocate one or more nodes of the second set from the second memory to the first memory such that the a utilization count for each of the nodes of the first memory is higher than each of the nodes of the second memory.
