Abstract
A method and apparatus for storing an associative key data set of associative elements representing a range, and an associated data set of associated elements, such that an associative element is extracted from memory in response to an input key, the range being represented by a lower boundary value and/or an upper boundary value, the method including: a) providing first and second storage areas for storing the respective data sets; b) ordering the associative elements according to priority precedence; c) storage a boundary value of each associative element in the first storage area in a location corresponding to this order, and d) storing each associated data set value in the second storage area in a location corresponding to the location of the associative element associated thereto.
