Abstract: When writing user data to a memory, a data synchronization indicator is set to a page to which the user data is written, depending on whether a data synchronization command is received from a host device. A guarantee for the user data requested by the host device may be provided, and operation efficiency of a storage device may be improved by reducing unnecessary operations when controlling the operation of the storage device.

Abstract: The present technology relates to a memory controller capable of shortening a time required for a read operation by storing a map segment output based on a result of counting the number of times a map entry is called in a host. The memory controller controlling a memory device includes a central processing device configured to receive a read request from a host and perform an operation for outputting data corresponding to the read request to the host, and a flash translation layer configured to search for a map entry indicating a mapping relationship between a logical block address and a physical block address by receiving the logical block address corresponding to the read request from the central processing device, and store a read count table based on a result of searching the map entry.

Abstract: A method for operating a data storage device includes storing an erase count corresponding to a physical address, as a reference value, in response to a first event; comparing a current value of the erase count with the reference value in response to a second event; and selectively performing a purge operation for the physical address, depending on a result of the comparing.
