ABSTRACT:
A mechanism is provided for efficiently storing a key and optionally additional data in an environment. A memory apparatus embodiment includes a plurality of memory banks and a conversion module. The number of memory banks is determined by at least the number of coordinates within an n-dimension format, each bank is associated to one of the coordinates within the n-dimension format. Each memory bank has at least a number of memory locations equal to the largest valid value for its associated coordinate. The conversion module converts a key into an n-dimension format, the n-dimension format defines a coordinate system where each coordinate represents a memory location within the associated memory bank. The conversion module stores the key into one memory location based on a policy which is dependent on the coordinates defined by the n-dimension format.
