Associative memory apparatus and routing apparatus |
摘要 |
An associative memory apparatus has such a structure as to reduce a load of an updating work and readily cope with an increase of the capacity. The associative memory apparatus outputs longest prefix match in only one searching operation, thereby shortening a processing time for the searching process. The apparatus comprises entry units, each of which includes a logical operating means outputting information about a bit length not masked in entry data when the entry data stored in its own entry unit coincides with bit data that is a key, and a search result outputting means outputting a search match information with respect to the search key only when the entry data stored in its own entry unit is entry data having the longest bit length not masked.
