The non-volatile memory device includes a current detection circuit for comparing, in data retrieve operation, storage information written in a non-volatile manner in a memory cell row with retrieval information in order to determine whether or not the storage information matches the retrieval information. The current detection circuit compares a data read current flowing through each bit line corresponding to each memory cell of a memory cell row storing the storage information with a data read current flowing through each bit line corresponding to each retrieval memory cell storing the retrieval information.
