    摘要: 7 A content addressable memory (CAM) cell signals a match/no-match condition between the content of a cell and the data applied to the comparison circuit by means of a voltage signal. In the associative memory mode, the associative memory comparison circuit compares the data on the bit lines to the data stored in the RAM cells. If there is a predetermined condition of either match or mismatch, a flag line driver transistor coupling the flag line to a bias voltage source such as ground changes its state of conductivity thereby altering the voltage on the flag line. The voltage signal thus produced indicates the match or mismatch condition.
