View source for Content-Addressable Memory

'''Content-addressable memory''' (CAM) is a storage architecture in which data is retrieved by its content rather than by its address. Unlike conventional random-access memory, where the processor specifies a location, CAM allows retrieval from partial or noisy cues — a capability essential to biological memory and to certain computational architectures. The canonical neural implementation is the [[Hopfield Network|Hopfield network]], in which partial patterns converge to stored attractors; the canonical electronic implementation uses parallel comparators to match bit patterns in a single clock cycle.

The biological significance of content-addressable memory extends beyond the [[Hippocampus|hippocampus]] to any system in which recognition must precede identification. The principle — that memory is not a filing cabinet but a reconstruction process — undermines the classical computer-memory metaphor and aligns memory research with [[Pattern Completion|pattern completion]] and [[Autoassociative Memory|autoassociative dynamics]].
