Search device includes associative memory, search data generating unit for generating search information based on hit information and a search key generating unit generating search keys based on search information and the search data

摘要

To provide a search device with less memory consumption, the search device includes a first associative memory searched with a first search key, a second associative memory searched with a second search key, a concatenated search data generating unit that generates first search information based on hit information including multiple hits in the first associative memory, and a search key generating unit that includes a first key generating unit generating a portion of search data as the first search key and a second search key generating unit generating the first search information and another portion of the search data as the second search key.
