  • Memory system and operating method thereof
    Patent number: 10997065
    Abstract: A memory system and an operating method thereof are provided. The memory system includes a buffer memory storing a plurality of meta-slices constituting meta-data, and a memory controller marking meta-slices being updated, among the plurality of meta-slices stored in the buffer memory, as dirty meta-slices, generating journal data including update information corresponding to the dirty meta-slices, and flushing the journal data together with one of the dirty meta-slices to a non-volatile memory device.
    Type: Grant
    Filed: August 14, 2018
    Date of Patent: May 4, 2021
    Assignee: SK hynix Inc.
    Inventors: Byung Min Ha, Ji Yeun Kang, Hae Lyong Song, Young Mi Yoon, Min Kyung Choi
  • Data storage device and operating method thereof
    Patent number: 10558562
    Abstract: A method for operating a data storage device includes determining an nth garbage collection throughput by multiplying a rate of a number of used pages of an open memory block to an amount of write data to be processed to a sum of the number of used empty memory blocks and an immediately previous garbage collection throughput average value; and performing a garbage collection operation based on the nth garbage collection throughput.
    Type: Grant

  • Memory system which stores meta-data and meta-log, and operating method thereof
    Patent number: 10553295
    Abstract: A memory system may include: a nonvolatile memory device suitable for storing write-requested data; and a controller including a first volatile memory region suitable for storing meta-data for the write-requested data and a second volatile memory region suitable for storing a meta-log for the meta-data, the controller may store the meta-data or the meta-log according to a logical address range of the meta-data.
