The invention relates to a content addressing method based on a hash chain table and a corresponding storage circuit. The storage circuit includes a storage unit, a control unit, a register interface and a data search comparison interface. The content addressing method adopts the methods of hash, chain, multi-character parallel storage, comparison and the like, resolves the problem in the prior art of use limit caused by the fact that a special process or a device is adopted to achieve the content addressing storage and the problems of small content addressing search speed, large consumption resources, difficulty in content addressing search depth and width expansion and the like in a traditional design method, has the advantages of being high in generality, high in search speed, high in hardware utilization rate, easy to expand and the like, and is not limited by the chip process or a field programmable gate array (FPGA) device.
