Low Power Asynchronous Transfer Mode with High Speed Using ZTCAM

Kanagavalli M, Sukumar P

In Modern Trends the demand for memory has been increased tremendously. The searching operation of data in memory is the main problem that faces user. It increases power consumption and access time. Ternary content addressable memory performs high speed lookup operation but when compared with SRAMs, TCAMs have certain limitation such as low storage density, relatively slow access time, low scalability, complex circuitry, and are very expensive. Thus in this paper two works has been carried out, first one is TCAM uses the benefits of SRAM by configuring it (with additional logic) to enable it to behave like, it named as ZTCAM, which emulates the TCAM functionality with SRAM. SRAM is more faster and reliable memory. The static is derived from the fact that it doesn’t need to be refreshed. In the proposed ZTCAM hybrid partitioning of TCAM table is used, which partitioned the given data into many layer with low power. The proposed approach mainly user of SRAM read operations for comparisons. Second work has to be designing Asynchronous Transfer Mode (ATM) .Here Z-TCAM has been used in Asynchronous Transfer Mode (ATM) switching network components as a translation table. Here Z-TCAM architecture has been designed using SRAM, Flip-Flops and Asynchronous Transfer Mode has been designed with STT-RAM (Spin Transfer Torque), as compared with SRAM, the STT-RAM consumes less power. Z-TCAM has been successfully simulated using Tanner EDA and also designed using 0.18 μm technology.
