Ternary content addressable memory with match line circuit for controlling potential of match realizing higher speed of search access

摘要

An object of the present disclosure is to provide a content addressable memory realizing higher speed of a search access. A content addressable memory includes: a plurality of memory cells; a match line coupled to the plurality of memory cells; a search line coupled to each of the plurality of memory cells; a match line output circuit coupled to the match line; and a potential changing circuit coupled to the match line and changing the potential of the match line.
