Ternary content addressable memory (TCAM) is a high-speed memory employed in network search engines which consume significant power. Many authors have provided efficient power solutions by proposing different match line schemes. This study proposes the use of energy recovering adiabatic logic scheme in the design of power-efficient TCAM. Two different innovative quasi-adiabatic TCAM (QATCAM) core cells are designed. The design is implemented in 180 nm complementary metal-oxide semiconductor technology with a power clock of 1.8 V on Cadence Virtuoso. It is found that the power dissipated by the proposed QATCAM cells is lower than its conventional counterparts. Adiabatic TCAM arrays are designed using adiabatic peripheral circuits. The proposed adiabatic TCAM core cells yield more considerable power savings even at higher frequencies up to 1 GHz.

高效准绝热三元内容可寻址存储器（QATCAM）的设计与分析

三元内容可寻址存储器（TCAM）是在网络搜索引擎中使用的高速存储器，它消耗大量电能。许多作者通过提出不同的匹配线方案提供了有效的电源解决方案。本研究提出了在能量效率高的TCAM设计中使用能量回收绝热逻辑方案。设计了两种不同的创新型准绝热TCAM（QATCAM）核心单元。该设计在Cadence Virtuoso上采用180 nm互补金属氧化物半导体技术实现，电源时钟为1.8V。发现，所提出的QATCAM单元所耗散的功率低于其常规对等方。绝热TCAM阵列是使用绝热外围电路设计的。所提出的绝热TCAM核心单元即使在高达1 GHz的更高频率下也可以节省更多功率。
