A controller may include a memory suitable for caching write data and map data corresponding to the write data; and a processor suitable for flushing the cached map data in a memory device, and then storing the write data in the memory device, wherein the map data includes location information of the write data.

Controller for recovering map segments in case of sudden power off and operating method thereof

A data processing system includes a host suitable for providing an access request; and a plurality of memory systems suitable for storing or reading data thereto or therefrom in response to the access request, wherein the host includes a host memory buffer suitable for storing a plurality of meta-data respectively corresponding to the plurality of memory systems, wherein each of the plurality of meta-data includes a first threshold value representing storage capacity for user data in a corresponding memory system among the plurality of memory systems, a second threshold value representing a number of read operations for logical block addresses (LBAs) of the corresponding memory system, a third threshold value representing a temperature of the corresponding memory system and respective LBAs of the plurality of memory systems.

Data processing system including a host distributing data across multiple memory systems and method for the same

A memory system including a nonvolatile memory device storing operation logs and map data; a volatile memory for temporarily storing the map data; and a controller flushing the map data from the volatile memory into the nonvolatile memory device by units of map data groups, and rebuilding the map data by selectively reading the map data by the units of map data groups from the nonvolatile memory device into the volatile memory according to the operation logs, wherein the operation logs indicate: locations of first and last pages to store the flushed map data; a start of an error management operation to a program error during the flushing of the map data; and a location of a last page storing normally flushed map data before an occurrence of the program error.
