Abstract: An operating method of a storage device including a nonvolatile memory device includes receiving a logical address and a write command for first data from an external device, determining whether the write command includes security properties, detecting whether second data written into the same logical address as the logical address exists according to a result of the determination, and writing the first data into a unit memory area in which the second is stored according to a result of the detection.

Abstract: There is provided an operation method of a memory system which includes a host and a storage device, and the operation method includes allocating a portion of a host memory included in the host for a host memory buffer to be used by a controller of the storage device, setting a set feature command such that the host memory buffer is enabled, setting a retention command including information about a response speed of the host memory buffer, selecting an operation mode of the host memory buffer, based on the retention command, and selecting one of a plurality of power states, which the controller supports, based on a performance objective of the operation mode of the host memory buffer.
