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.
