Abstract
A method for arranging and storing data in a memory and for extracting the data from the memory in response to an input key, including the steps of (a) providing at least a first array having at least two dimensions, the first array consisting of rows and columns, the first array for storing a plurality of range boundary information; (b) providing at least a second array having at least two dimensions, the second array consisting of rows and columns, the second array for storing a plurality of associated data entries; (c) processing sets of range information to produce, for each of the sets: (i) range boundary information including at least one range-boundary value, the range boundary information being associated with a particular one of the associated data entries, and (ii) range validity information, and (d) storing the range boundary information within the first array.
