| 1. A Content Addressable Memory comprising:
a two-dimensional array of content addressable memory sub-blocks, each sub-block comprising a cell array that facilitates
an operation on data and a sub-block priority encoder that processes results of the operation;
a plurality of data inputs, each coupled to a respective sub-block in a first column of the array;
a plurality of interconnections, each coupled to a pair of adjacent sub-blocks in a row of the array, that pass data and results
of the operations across rows of the array; and
a plurality of data outputs, each coupled to a respective sub-block in a last column of the array.
