Claim 21:
22. A method of implementing a network switch that includes one or more static random access memory (SRAM) pools and at least one spillover ternary content addressable memory (TCAM) pool, wherein each entry of the one or more SRAM pools includes a code field including one or more codes and a value field including rule comparison data, the method comprising:
with the network switch:
sending a search key to at least one of the one or more SRAM pools and selecting one of the entries within the at least one of the one or more SRAM pools;
evaluating each of the codes of the one of the entries based on the search key and the value field thereby determining which of the codes are satisfied by the search key; and
determining if the search key is a match for the one of the entries based on a combination of the codes that are satisfied by the search key and which of the codes are not satisfied by the search key.
