  • Storage device including nonvolatile memory device and operating method thereof
    Patent number: 12093185
    Abstract: A storage device includes a nonvolatile memory device and a memory controller. After writing first data at the first page, the memory controller writes second data at a second page. The memory controller generates first check data corresponding to the first data and second check data corresponding to the second data. The memory controller recovers the first and second physical addresses and the first and second logical addresses based on the second check data.
    Type: Grant
    Filed: May 30, 2022
    Date of Patent: September 17, 2024
    Assignee: Samsung Electronics Co., Ltd.

  • Operation method of memory controller and operation method of storage device including the same
    Patent number: 10824564
    Abstract: An operation method of a memory controller which is configured to control a nonvolatile memory device includes receiving a command from the outside, calculating a delay time based on a currently available write buffer, a previously available write buffer, and a reference value, and processing the command based on the delay time.
