摘要: This paper proposes a Pai-Sigma matchline scheme to reduce the compare (search) power of a ternary content addressable memory (TCAM). The proposed matchline does not incur the issues of charge sharing and short circuit current, which typically exist in the hybrid nand-nor matchline. Moreover, the switching activity of the search lines of a TCAM with the proposed matchlines is low. A 32×64-bit TCAM with the Pai-Sigma matchlines is implemented to demonstrate the low-power feature. Results show that the compare power of the TCAM can achieve 60% energy reduction compared with the conventional nor-type TCAM. Also, the energy consumption per bit per search of the TCAM is only 2.287 fJ/bit/search. 其他題名: TVLSI 出版者: New York, NY: IEEE 出版日期: 2012-10-01 出處: IEEE transactions on very large scale integration (VLSI) systems, 2012-10, Vol.20 (10), p.1909-1913 資源來源: IEEE Electronic Library (IEL) 版權: 2015 INIST-CNRS 識別號: ISSN: 1063-8210 識別號: EISSN: 1557-9999 識別號: DOI: 10.1109/TVLSI.2011.2163205 識別號: CODEN: IEVSE9
