Abstract
An electronic device emulating nonvolatile memory includes: a first memory including a data block in which data is stored and a metadata block in which metadata relating to the data is stored; a second memory in which data to be used by the electronic device is stored; and a processor configured to manage data of the first memory and the second memory. The processor may generate a random value for distinguishing between first data and other data when the first data is stored in the first memory, include the random value in the first data and then store the first data in the data block, and store, in the second memory, a password value obtained by encrypting information on the first data based on the random value and a roll-back key.
