ABSTRACT:
A plurality of content-addressable-memory sub-arrays simultaneously performs a parallel comparison between data sequences arranged in a row direction of memory cells and a search data sequence input from outside, and outputs a result of the comparison for each data sequence. A first input pin receives an input of the search data sequence. A second input pin receives an input of a search data sequence arbitrarily designating a content-addressable-memory sub-array. Each of the content-addressable-memory sub-arrays includes an activation control unit that controls activation of the content-addressable-memory sub-arrays based on the search data sequence.
