摘要： A memory system, including a flash memory including multiple memory blocks, and a controller configured to erase each of the memory blocks using multiple steps. The controller stores, for each of the memory blocks, metadata indicating which of the multiple steps have been completed, and erases each of the memory blocks based on the stored metadata.

摘要： A memory system includes a flash memory including a block having first sub-blocks and second sub-blocks different from each other, the second sub-blocks including free pages only; and a controller configured to erase the flash memory in units of the sub-blocks, and in a garbage collection operation, the controller is configured to copy data of a valid page of the first sub-blocks to at least one of the second sub-blocks.

摘要： Disclosed is a method of writing data in a storage device including a nonvolatile memory device. The method includes receiving write data with a write request, detecting a number of free blocks, if the detected number of free blocks is less than a threshold value, allocating a log block only in accordance with a sub-block unit, but if the detected number of free blocks is not less than the threshold value, allocating the log block in accordance with one of the sub-block unit and a physical block unit, wherein the sub-block unit is smaller than the physical block unit.
