A storage device may transmit a command set to a memory, set a plurality of flag bits based on transmission status of a plurality of commands included in the command set, respectively, and determine whether an error occurred in the process of transmitting the command set to the memory based on the plurality of flag bits. Each of the plurality of flag bits has a first value or a second value, and the command set includes a reset command, a command set start command, and a command set end command.

Storage device for determining successful transmission of commands and methods of operation

A storage device may determine first priority parameters and second priority parameters for a plurality of memory dies on the basis of temperatures of the plurality of memory dies measured at a first time point and a second time point. The storage device may determine priorities of the plurality of memory dies for a read operation or a write operation on the basis of the first priority parameters and the second priority parameters for the plurality of memory dies.

Storage device determining priorities on the basis of temperatures of memory dies and temperature variations, and method thereof

Provided herein may be a memory system and a method of operating the same. The memory system may include a memory device including a plurality of memory blocks, the memory device being configured to output voltage information indicating whether an unstable state of an input voltage has occurred, the input voltage being provided to the memory device from an external power source, and a memory controller configured to store a read count indicating a number of times that one or more read operations are performed on each of the plurality of memory blocks and to control the memory device to move data stored in a first memory block for which the read count exceeds a threshold count to a second memory block, and configured to adjust the threshold count based on the voltage information.

Memory system and method of operating the same

A memory system and a memory controller are disclosed. By determining whether an error has occurred in target data stored in a predetermined target memory area of the memory device and determining, in response to whether an error has occurred in the target data, the magnitude of the supplied power based on a first operation parameter selected among predetermined candidate operation parameters in connection with the magnitude of the supplied power, the memory controller may stably drive a firmware, and may handle an operation error of the firmware due to a change in external environment.

Memory system and memory controller determining a magnitude of a power supplied to the memory controller when error has occurred in target data

A data storage apparatus may include a storage and a controller. The storage includes a plurality of planes each composed of a plurality of memory blocks, and is divided into a first region and a second region. An original of system data and a copy of the system data are stored in the first region. The controller is configured to perform a relief operation of moving the copy of the system data stored in a source memory block of the first region to a victim plane and switching the source memory block to a region replaceable with the second region.

Data storage apparatus with extended lifespan and operation method thereof

Provided herein may be a storage device and a method of operating the same. The storage device may include a memory device and a memory controller. The memory device may include first memory blocks and second memory blocks. The memory controller may be configured to control the memory device so that valid data stored in a victim block, among the first memory blocks, is stored in a target block, among the second memory blocks, based on a result of a comparison between an amount of valid data stored in the victim block and a reference value. Each of the first memory blocks may include memory cells each configured to store n bits, where n is a natural number of 2 or more. Each of the second memory blocks may include memory cells each configured to store m bits, where m is a natural number less than n.

Storage device performing garbage collection and method of operating the same

A storage device may include a memory device and a memory controller. The memory device may include a memory block including a plurality of pages. When a sudden power off is detected in which power supplied to the memory device is abnormally interrupted during a normal program operation on one page among the plurality of pages, the memory controller may control the memory device to perform a dummy program operation on a selected page among the plurality of pages after the sudden power-off. The memory controller may control the memory device to perform the normal program operation and the dummy program operation by using an Incremental Step Pulse Program (ISPP) method. The memory controller may control the memory device to perform the dummy program operation in a smaller number of program loops as compared with the normal program operation.
