Abstract: PROBLEM TO BE SOLVED: To provide a match line circuit and match line method for low electric power retrieval in the contents address assignable memory. SOLUTION: Hit is output (emitted) when match line stands from LOW electric level to higher match electric voltage. The Matching voltage is the continuity threshold voltage of N channel field effect transistor(FET), generally is smaller than half of the source power voltage. The circuit and method to cut-off the penetrating current by each unmatch entry, by control signals which are carefully timed at the end of the short period of matching are disclosed.
