Dual Pai-Sigma Segment Matchline for low power Ternary CAM
نویسندگان
چکیده
This paper proposes a Dual Pai-Sigma Segment Matchline scheme to reduce the search (compare) power of a Ternary Content Addressable Memory (TCAM). The proposed Matchline does not incur the issues of short circuit current and charge sharing, which typically exist in the hybrid NAND-NOR Matchline. The proposed scheme is designed using 6T NAND&NOR TCAM cells and 4T NAND & NOR TCAM cells and their performance is compared. Results shows that the search power of the TCAM can achieve 60% power reduction compared with the conventional Single Pai-Sigma Matchline. And the delay is calculated as ns. And also the power delay product of the proposed scheme very less compared to conventional method.

Ternary Content Addressable Memory Types And Matchline Schemes
Ternary Content Addressable Memory (TCAM) used in many application like network routers and packet classification. To reduce the power consumption of matchlines, the matchline partitioning scheme is used. Matchline is partitioned into NOR and NAND type matchline. If NAND (NOR) type TCAM cell is used then NAND (NOR) type matchline is used. NOR type TCAM has feature of high speed and high compare...
متن کاملThe Effect of DTMOS Transistors on the Performance of a Memristor-based Ternary CAM Cell in Low Power Applications
This paper proposes the use of DTMOS transistors in a memristor-based ternary CAM (MTCAM) instead of MOSFET transistors. It also evaluates the effect of forward body biasing methods in DTMOS transistors on the performance of a MTCAM cell in write mode. These biasing methods are gate-to-body tying (called DT1), drain-to-body tying (called DT2), and gate-to-body tying with a voltage supply of 0.1...
متن کاملDesign of a Low Power Content Addressable Memory (CAM)
Conventional CAM designs typically take up significantly more area, power, and sometimes delay compared to location addressed memories of the same capacity. If these penalties are traded off against each other, there will be many new applications for CAMs that are not feasible or practical today. In this study using EDP as a metric, we analytically evaluate individual CAM design techniques prev...
متن کاملLie ternary $(sigma,tau,xi)$--derivations on Banach ternary algebras
Let $A$ be a Banach ternary algebra over a scalar field $Bbb R$ or $Bbb C$ and $X$ be a ternary Banach $A$--module. Let $sigma,tau$ and $xi$ be linear mappings on $A$, a linear mapping $D:(A,[~]_A)to (X,[~]_X)$ is called a Lie ternary $(sigma,tau,xi)$--derivation, if $$D([a,b,c])=[[D(a)bc]_X]_{(sigma,tau,xi)}-[[D(c)ba]_X]_{(sigma,tau,xi)}$$ for all $a,b,cin A$, where $[abc]_{(sigma,tau,xi)}=ata...
متن کاملTCAM Core Design in 3D IC for Low Matchline Capacitance and Low Power
Ternary Content Addressable Memory (TCAM) has been an emerging technology for fast packet forwarding, commonly used in longest prefix match routing. Large table size requirements and wider lookup table data widths have led to higher capacity TCAM designs. However, the fully parallel characteristic of TCAM makes large TCAM design more challenging and limits its capacity due to intensive power co...
