    摘要: According to the present technology, a storage device includes a nonvolatile storage area including a plurality of backup memory blocks each including a plurality of memory cells respectively connected to a plurality of word lines, and a controller configured to control the nonvolatile storage area to determine a target memory block in which data is to be stored among the plurality of backup memory blocks, determine a reference word line among the plurality of word lines coupled to the target memory block, and perform a pre-conditioning operation of programming dummy data to memory cells connected to at least one of remaining word lines except for the reference word line among the plurality of word lines coupled to the target memory block.

    摘要: A method performed by a controller comprising assigning a first status indicator to entries in a first address line in a volatile memory belonging to a first region of an LUT stored in a non-volatile memory, and a second status indicator to entries in the first address line in the volatile memory belonging to a second region of the LUT, setting either the first or second status indicator to a dirty status based on whether a cache updated entry at an address m in the volatile memory belongs to the first or second region of the LUT, and writing, based on the dirty status of the first and second status indicator at the address m, all entries in the volatile memory associated with the first region or the second region containing the updated entry to the non-volatile memory.
