A range-matching TCAM using the proposed range-matching cell increases storage efficiency by up to 2.5 times compared to a conventional TCAM. In addition, charge recycling with the proposed static TCAM cell can reduce the search-line power. The 512 times 144b prototype chip, fabricated in a 1.2V 0.13μm CMOS process, achieves a 4.8ns search time at 0.59fJ/b/search
