PURPOSE: A nonvolatile memory device, a repair circuit, and a method for reading CAM(Code Addressable Memory) data are provided to shorten loading time of the CAM data by reading a plurality of CAM data with a multi plane method. CONSTITUTION: A memory cell array(120) includes a plurality of planes. A plurality of CAM data are stored in an independent plane. A redundancy cell array(130) replaces a memory cell array. A CAM data reading unit(200) reads the plurality of CAM data from each plane and stores the plurality of CAM data in response to a CAM data read command. A repair circuit outputs a repair control signal by referring to the CAM data stored in the CAM data reading unit.
