A memory system may include: a nonvolatile memory device; and a controller suitable for generating first map information which maps physical addresses of the nonvolatile memory device to logical addresses received from a host, selecting some segments of the first map information as second map information, and outputting the second map information to the host, the controller may determine whether the second map information is updated, and may determine updated map segments as third map information, and the controller may output information to the host indicating the third map information corresponding to a command received from the host.

Apparatus for transmitting map information in memory system

A memory system may comprise: a memory device including a plurality of memory dies; and a controller including a first memory, Wherein the controller may store data segments of user data, corresponding to a plurality of commands received from a host, in the first memory, controls the memory device to sequentially store the data segments in the memory dies through interleaving, may update map segments of map data corresponding to storage of the data segments in the memory dies, may store the map segments in the first memory, controls the memory device to store the map segments stored in the first memory in the memory dies, and may assist the host in storing the map segments, stored in the first memory, in a second memory in the host.

Memory system and operating method thereof

A memory system includes a memory device including a plurality of memory dies that store data, and a controller coupled to the plurality of memory dies through a plurality of channels, and suitable for generating and managing map data in which a logical address of a host is corresponding to a physical address of the memory device, wherein, when logical information on two or more consecutive logical addresses requested to be accessed and physical information on two or more consecutive physical addresses corresponding to the two or more consecutive logical addresses are inputted from the host, the controller sequentially performs access operations on the physical addresses corresponding to the received physical information.

Method and apparatus for performing access operation in memory system utilizing map data including mapping relationships between a host and a memory device for storing data

A memory system may include a memory device suitable for storing data and a controller suitable for generating and managing map data comprising a logical address of an external device and a physical address of the memory device corresponding to the logical address. The controller uploads at least some of the map data to the external device and uploading a latest version of the uploaded map data to the external device again based on dirty information or access information. The dirty information indicates whether a physical address corresponding to a logical address included in the uploaded map data has been changed. The access information indicates whether an access request for the logical address included in the uploaded map data from the external device has been made.

Apparatus and method for managing meta data in memory system

A data processing system includes: a host suitable for checking battery state information and determining a battery grade based on the battery state information; and a memory system suitable for storing information indicating the battery grade provided from the host, determining a method of performing a background operation based on the battery grade, and performing the background operation based on the determined method.

Data processing system and operating method thereof

A method for operating a controller that controls a memory device includes: replacing a bad block of a superblock with a replacement block to form a reproduced superblock; controlling the memory device to perform a program operation on the reproduced superblock according to an interleaving scheme; moving data stored in the replacement block to a pseudo-replacement block when the program operation on the reproduced superblock is completed; and releasing the replacement block from the reproduced superblock.

Controller for managing superblocks and operation method thereof

A memory system may include a plurality of dies; and a controller coupled to the plurality of dies through a plurality of data paths, the controller being suitable for transmitting first data received from a host and second data obtained through an internal operation in parallel through the plurality of data paths.

Memory system including plural regions storing data and operating method thereof

A memory system includes a memory device configured to store a piece of data in a location which is distinguished by a physical address and a controller configured to generate a piece of map data associating a logical address, inputted along with a request from an external device, with the physical address and to transfer a response including the piece of map data to the external device.

Memory system for utilizing a memory included in an external device

A memory system includes a memory device including a plurality of source dies, wherein each of the plural source dies includes a plurality of memory blocks; and a controller suitable for configuring a super block by selecting a memory block of which a maximum erasable count value is lowest in each of the plurality of dies.

A data processing system may include: a host suitable for including a first physical address corresponding to a first logical address in a first command, wherein the first physical address and the first logical address are associated with data, and sending the first command with the first physical address; and a memory system suitable for performing an operation corresponding to the first command by using the first physical address received from the host, and sending a result of the performed command operation to the host as a response, the host may check a time difference between a first time point that the first command is sent and a second time point that the response corresponding to the first command is received, and may determine whether to use the first physical address in a next command, based on a result of the time difference check.

Apparatus for transmitting map information in a memory system

A memory system may include: a memory device including plural memory dies each having plural memory blocks; and a controller configured to control the memory device to independently perform an operation to each of the memory dies, wherein the controller controls the memory device to perform a foreground operation to a first one among the memory dies while performing a background operation to a second one among the memory dies.
