Abstract

See full text

A content addressable memory (CAM) implementation using random access memory (RAM) and a method for operating the implementation are described, wherein the RAM is divided into smaller, individually addressable units, which are addressed by a subword of the applied keyword, and the outputs of which are bitwise ANDed. The result of the bitwise AND operation is used to activate the matching lines of the CAM implementation. The new implementation allows the use of conventional circuit design.
