ABSTRACT:
A content addressable memory (CAM) device (100) may include a CAM array (102), a CAM array access circuit (104), and a preclassifier circuit (106). A preclassifier circuit (106) may selectively modify portions of an input data value before such an input data value is applied to a CAM array (102). In particular embodiments, a preclassifier circuit (106) may compare a compare portion of an input data value to one or more ranges. If such a portion falls within a range, a preclassifier may substitute a compare portion with a range code value to form a modified input data value.
