Abstract

See full text

A ternary content-addressable cell is configured to compare an input binary data item present on an input terminal with two reference binary data items, and to output a match signal on a match line. The cell includes: a first storage circuit (storing a potential representing the first reference binary data item) and a second storage cell (storing a potential representing the second reference binary data item). A comparison circuit is connected to the first and second storage circuits and to the input terminal SL. A comparison node presents a potential representing the comparison of the input binary data item with the first and second reference data items. The comparison node is connected to an output stage, and the output stage is connected to the match line. The signal on the match line is based on the potential of the comparison node.
