node n 1 is de coupled from the logic high value of control line c 1 via turned off transistor 708 thus turned off transistor 708 prevents a change in the value of match line match 1 due to the value stored in cam cell 801 in this way cam cell 801 is masked from the compare operation as a result whether sram cell 301 a stores a logic high value or a logic low value cam cell 801 effectively stores a logic u201c don 39 t care u201d value if mask memory cell 801 b stores a logic high value node n 1 is coupled to the logic high value of control line c 1 via turned on transistor 708 as a result cam cell 801 participates in the compare operation if cam cell 801 stores a matching logic high value sram cell 301 a node n 1 stores a logic high value then node n 1 is de coupled from match line match 1 due to turned off transistor 327 as a result match line match 1 remains in a logic low state thereby indicating a match condition if cam cell 801 stores a non matching logic low value sram cell 301 a node n 1 stores a logic low value then node n 1 is coupled to match line match 1 through turned on transistor 327 as a result match line match 1 is pulled up to the logic high value of control line c 1 through turned on transistors 327 707 and 708 thereby indicating a no match condition to compare a logic low compare data value to cam cell 801 data line d 1 is.
