  • Patent number: 6691131
    Abstract: The invention relates to a method for implementing a functional memory and to a memory arrangement. The memory is implemented as a directory structure comprising a tree-shaped hierarchy having nodes at several different hierarchy levels. In the directory structure, pointers are first added to nodes whose table contains a given first number of elements and which are width-compressed nodes. To maximize the performance of the functional trie structure, addition of a pointer to an individual width-compressed node is permitted until the number of pointers in the node corresponds to a given predetermined threshold value that is smaller than said first number. The width-compressed node is converted to a cluster of nodes made up by a parent node (N50) and separate child nodes (N51 . . . N54) as soon as the number of pointers to be accommodated in the width-compressed node exceeds said threshold value.
