  • Patent number: 11561853
    Abstract: 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.

  • Patent number: 11543990
    Abstract: 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.

  • Patent number: 11500768
    Abstract: 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.

  • Patent number: 11380416
    Abstract: 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.
