Abstract: A nonvolatile memory device with high security is provided. A nonvolatile memory device comprises a memory cell array and a secure module, wherein the secure module is configured to process first data including information about the nonvolatile memory device stored in the memory cell array to generate a first password key, process second data including information about the nonvolatile memory device stored in the memory cell array to generate a second password key, generate a public key and a secret key by a public-key cryptography algorithm, using the first password key and the second password key, and provide the first password key, the second password key, the public key, and the secret key to the memory cell array, the memory cell array is configured to store the first password key, the second password key, the public key, and the secret key, the second data is different from the first data, a value of the first password key value and a value of the second password key are prime numbers, and the public key is provided to a host connected to the nonvolatile memory device.
