摘要：
A range-matching cell (RMC) includes bit lines (BL); a word line (WL); a match line (ML); search lines (SL); a memory cell (100); a first comparator (110) connected to the memory cell; a second comparator (120) connected to the first comparator, a ground voltage and a predetermined voltage. The comparators conduct a comparing operation in responsive to operator data. Instead of the conventional TCAMs employing 0, 1, and X (don't care) bit, a CAM utilizing the RMC can conduct a comparing operation with less memory by storing the operator data 0 and 1 in advance. Accordingly, memory-use efficiency can be increased.
