Associative memory bit cells are disclosed for selectively producing binary or ternary content-addressable memory lookup results. Associative memory bit cells are grouped together to act as n binary content-addressable memory cells (CAM) bits or m ternary content-addressable memory (TCAM) bits, with n>m>0. Based on the programming of the associative memory bit cells and the selective application of search values (based on whether they are acting as CAM or TCAM bit cells), the appropriate determination is made as to whether or not to signal a hit or a miss based on the current input search values. These associative memory bit cells can also be combined to provide error protection for either of their operating modes. Error protection can be used to enable a correct result when e bit errors occur in the stored values in the associative memory bit cells.
