Abstract
A key generating method includes obtaining a first error correcting code (ECC) for original data, obtaining read data from a cell array of a memory comprising the original data, generating a second ECC for the read data, obtaining a location of a cell in which an error occurs from the cell array of the memory in response to the second ECC being different from the first ECC, and generating a key for the memory based on the location of the cell in which the error occurs.
