The present disclosure relates to a memory system capable of encrypting and storing data, and a memory controller. The memory controller may include a first interface configured to perform data communication with a first external device, a second interface configured to generate a signal for controlling an operation of a second external device and transmit the signal; and a processor configured to receive, from the first external device, a data write command to write data to the second external device, encrypt the data by using one of a plurality of keys stored in a key area provided in the first external device in response to the data write command, and then control the encrypted data to be written to the second external device.

Memory system, memory controller and operation method thereof for encrypting data stored in a nonvolatile memory

A storage device may receive, from an external device, a target read recovery level indicating information on a read command execution completion time and an error recovery amount requested by the external device, may read, from a memory, data requested by a read command transmitted by the external device, and may transmit, to the external device, a response regarding a result of executing the read command transmitted by the external device within the read command execution completion time indicated by the target read recovery level.

System and storage device for executing read command using read recovery level and methods of operation

A storage device includes a memory controller, including: a controller configured to receive a read command from an external device, determine whether the read command is a general read command or a read-ahead command; continue an erase operation or a program operation currently in progress if the read command is a read-ahead command; and temporarily suspend an erase operation or a program operation currently in progress and process the read command if the read command is a general read command.
