Abstract
Techniques for extending memory addressing with more accessing range are disclosed. According to one aspect of the techniques, an apparatus for extending addressing space comprises a plurality of extended memories, each being allocated an unique identifier, a direct addressing memory reserving a data cell as a public identifier cell for receiving the identifier of each of the extended memories to be accessed, a decision unit determining that which one of the extended memories is to be accessed by comparing an identifier received by the public identifier cell with the identifier of each of the extended memories, and a mapping unit mapping one of the extended memories determined by the decision unit to be accessed onto the direct addressing memory so that the one of the extended memories can be indirectly accessed by directly accessing the direct addressing memory.
