摘要:
Systems, devices, and methods, including executable instructions are provided for content addressable memory (CAM). One method includes defining the CAM into an array of data words having M rows and N columns, with each of N and M being greater than one. The data words of the CAM are arranged according to a 2-dimensional priority scheme. Data words outside a selected 1×M column are masked to be ignored in determining a match, and the CAM is searched. Each search includes N compare cycles and each compare cycle having a different 1×M column selected. A highest priority match per compare cycle is pipelined from a priority encoder with the pipelined matches arranged to communicate a priority order in a first dimension of the 2-dimensional priority scheme.
