ABSTRACT
For searching the data parallely the most widely used hardware is Ternary Content addressable memory (TCAM).The parallel searching gives high speed but also consumes high power. For higher search speed applications, NOR type matchline TCAMs are useful and NAND type matchline TCAMs are useful for low power applications. The NOR-type matchline TCAM requires high power, therefore, the reduction of its power consumption is the objective of many described designs. Here, a novel precharge free TCAM is proposed .The proposed TCAM power consumption is 20% less than the NOR type matchline TCAM. Simulations performed with cadence 45-nm technology.
