Abstract
A memory system has a plurality of memory stages in which each stage stores a respective portion of a data table. A request for reading an entry of the table is processed serially by the memory stages, and each stage narrows the range of table entries possibly storing the requested data. Based on the results of the previous stages, the final stage is able to quickly determine whether the requested data is stored in the data table and, if so, to retrieve the requested data from such table.
