A nonvolatile memory device includes at least a memory cell block including memory cells that are coupled to a plurality of word lines, respectively, and store data; a content addressable memory (CAM) block including CAM cells that are coupled to the word lines, respectively, and store chip information for operations of the nonvolatile memory device; and a block switching circuit configured to couple the word lines with global word lines; and a voltage supply circuit coupled to the global word lines, for supplying a first read voltage to a selected global word line while supplying a first pass voltage to unselected global word lines in reading the memory cell block, and supplying a second read voltage to a selected global word line while supplying a second pass voltage to unselected global word lines in reading the CAM block, wherein the second pass voltage is lower than the first pass voltage. |
