Content-addressable memory (associative memory) with early prediction, later correction and unbalanced sampling

摘要

Circuits and methods for performing search operations on an array of content addressable memories (CAM) are provided. A system for searching a CAM includes a circuit that selectively activates a main search action (130) of a two-stage CAM search while a pre-search action (100) of the two-stage CAM search is still active.
