Abstract
A data storage device includes a memory device including a whitelist storing one or more program contexts for identifying input/output (I/O) operation, and a control circuit including a whitelist managing circuit configured to determine whether a write request is allowable by comparing the whitelist with one or more program contexts transmitted with the write request from a host. The program contexts may be generated using program counter values corresponding to call operations performed by the I/O operation.
