A data storage apparatus includes a nonvolatile memory device including a dump region configured to temporarily store data according to a state of applied power; and a controller configured to monitor health information of the dump region of the nonvolatile memory device, generate environmental information corresponding to a power loss protection (PLP) operation based on the health information, and share the environmental information with an external device.

Data storage apparatus and operating method thereof

A memory system includes a memory device including a first memory block used for power-loss data protection and a controller coupled to the memory device. The controller includes a hardware layer and a firmware layer. The hardware layer checks whether at least one write data entry belongs to a programmable range in the memory device after power loss occurs, determines whether a logical address associated with the at least one write data entry is repeated, and programs the at least one write data entry in the first memory block.

Apparatus and method for power-loss data protection in a system

A memory system which stores a journal including mapping change information, either in a first memory area or a second memory area, depending on available space of a memory device included in the memory system, being greater than a threshold.

Memory system for determining a memory area in which a journal is stored according to a number of free memory blocks

Provided herein may be a memory controller and a method of operating the same. The memory controller may include a SPO detector configured to output a detection signal when a SPO is detected, a memory buffer configured to store host data, and a power loss controller configured to, based on the detection signal, receive dump data corresponding to the host data, store the dump data and a dump age corresponding to the dump data, and output the dump data and the dump age to a memory device, wherein the dump age indicates a number of times that different items of host data have been dumped from the memory buffer to the power loss controller, and the power loss controller is configured to control a recovery operation corresponding to the SPO based on the dump age being received from the memory device.

Memory controller for controlling power loss recovery and method of operating the same

A data storage apparatus includes a storage including a plurality of planes, which include a plurality of pages, and a controller configured to control the storage to read data by grouping the plurality of pages as a page group in an interleaving unit, manage pages in which valid data are stored, among the plurality of pages, as a first bitmap table, and manage a second bitmap table generated by compressing the first bitmap table in a page group unit.

Data storage apparatus and method for managing valid data based on bitmap table

A storage device for providing an improved security function may include a nonvolatile memory device, a position information generator generating first position information indicating a first geographical position of the nonvolatile memory device when an authentication request is input, a user information storage storing user information for accessing the nonvolatile memory device, the user information including second position information, and an access controller obtaining, in response to an authentication request provided from an external host, the first position information from the position information generator, and disposing of data stored in the nonvolatile memory device depending on whether the second position information included in the user information matches the first position information.

Storage device and method of operating the same

A memory system may include: one or more memory devices each including a plurality of memory cells for storing data; a memory for storing meta data associated with the stored data; and a memory controller in communication with the memory and the one or more memory devices and for loading the meta data from the memory, and generating first meta page based on the meta data according to a first layout, and storing the first meta page in the memory device.

Memory system and method for operating memory controller included therein

Embodiments of the present disclosure relate to a memory system and an operating method of the memory system. According to embodiments of the present disclosure, a memory system may include a main core for executing an operation of a first layer and a plurality of sub-cores for executing an operation of a second layer, and the main core may control, when executing a shutdown command received from a host, the plurality of sub-cores so that a second sub-core stores a meta data segment to be processed by a first sub-core among the plurality of sub-cores.

Memory system and operating method of memory system

A memory system, a memory controller and an operating method are disclosed. By dividing a read count table including read count values respectively for a plurality of memory blocks into one or more read count table segments each including one or more read count values of a resolution, and managing one or more flags respectively corresponding to the read count table segments, and set the flag corresponding to the read count table segment in which at least one read count value is changed among the read count table segments, it is possible to minimize additional operational costs required to recover the read count table upon occurrence of an SPO.

Memory system, memory controller and method for operating memory controller

A data storage device may include: a memory array comprising a plurality of blocks, each block including a plurality of pages and a controller in communication with the memory array and comprising a memory buffer, the controller configured to maintain attribute information associated with each block and each page of the memory array, the controller further configured to read data from a requested page in the memory array responsive to an external request, store the read data in a first region of the memory buffer to output the read data responsive to the external request, and copy the read data from the first region of the memory buffer into a second region of the memory buffer upon a determination based on the attribute information that the requested page is included in a supposed-to-be-erased region.

Data storage device with reduced memory access operation method thereof and controller therefor

Provided herein may be a memory controller, a memory system having the same, and a method of operating the same. The memory controller may include an operating environment determiner configured to determine an operating environment of a memory device based on at least one of surrounding environment-sensing data, and a central processing unit (CPU) configured to determine operating characteristics of the memory device required in the determined operating environment, select a policy depending on the determined operating characteristics, and control an operation of the memory device based on the selected policy.
