Abstract

Content Addressable Memory (CAM) is a type of solid-state memory that prioritizes data content above storage location for data retrieval. TCAMs are employed as specialized memory in high-speed networking equipment such as routers, firewalls, and NATs. Soft-error tolerant TCAMs are required in high-reliability network applications such as military and defense systems to prevent data corruption or errors caused by radiation. To speed up the search, partial keys and parity-based logic are utilized, and a new TCAM is used because it can handle several bit-flip faults. The suggested TCAM makes the TCAM more resilient and corrects various bit-flip problems. TCAM uses the generated X-keys and an X search to detect multiple bit flip issues. If the keys match in more than one spot, a soft error is assumed, and the backup ECC-SRAM is utilized to update the TCAM words. The suggested CAM employs both the genuine data bits and the additional one-bit parity segment. We only get the parity bit to determine how many "1s" are even or odd. Driving intensity is increased by one parity bit for a single mismatch, while sensing delay is cut in half. Because only one TCAM is required, the proposed TCAM has a compact hardware footprint. The ease of implementation of parity-based TCAM aids in the creation of fault-tolerant packet filters.
