Abstract

A search key lookup system including a hash table having a plurality of entries and a function generator is disclosed. The function generator can be coupled to the hash table and configured to receive a key and to provide a first function and a second function. The first function can be a Cyclic Redundancy Code (CRC) type function and the second function can be an Error Checking and Correcting (ECC) type function. Further, an address of the table can include a concatenation of the results of the CRC and the ECC type functions.
