Abstract
A search pattern is generated based on an input search word comprising a first sequence of bits. The search pattern comprises a representation of the input search word and a representation of an inverse of the input search word. The search pattern is provided as input to search lines of a ternary content-addressable memory (TCAM) block. A subset of the search lines is set to a logical high state based on a first portion of the input search word being designated as don't-care bits. The search pattern causes at least one string in the CAM block to be conductive and provide a signal in response to a data entry stored on the string comprising a second portion of the input search word that excludes the don't-care bits. A location of the data entry is determined and output.
