Abstract
A content addressable memory chip which can perform a high speed search with less error is provided. A match amplifier zone determines coincidence or non-coincidence of search data with data stored in the content addressable memory cells in an entry of a CAM cell array, according to the voltage of a match line. The match amplifier zone comprises one or more NMOS transistors and one or more PMOS transistors. The match amplifier zone has a dead zone to an input of a voltage of the match line, and has a property that no flow-through current is present in the match amplifier zone.
