    Abstract: A storage device includes: a non-volatile memory configured to include a plurality of blocks having a plurality of word lines and to write data to the blocks or to erase data of the blocks; and a splitter configured to obtain write times for a plurality of word lines of a first block of the blocks while the non-volatile memory writes data in the first block, and to command the non-volatile memory to perform an erase operation on a second block of the blocks by the reference time when a write time for one of the word lines is shorter than the reference time.

    Abstract: An operating method of a memory controller configured to control a memory device including memory blocks each for storing a plurality of pages is provided. The operating method includes transferring a program command to the memory device based on a write request from a host, updating a valid page bitmap representing validity of a plurality of pages based on valid page information received from the memory device, calculating a fragmentation ratio representing a segmentation degree between at least one valid page and at least one invalid page of a memory block based on the valid page bitmap, determining source blocks among the memory blocks in ascending order of fragmentation ratios, and performing garbage collection on the source blocks.

    Abstract: A storage device includes a non-volatile memory including a plurality of memory blocks and a storage controller configured to control a read operation of the non-volatile memory. The storage controller receives power-off time information indicating a power-off time point at which the storage device is powered off, and power-on time information indicating a power-on time point at which the storage device is powered on, when the storage device is switched from a power-off state to a power-on state. The storage controller stores a power-off time stamp corresponding to the power-off time point and a power-on time stamp corresponding to the power-on time point in the non-volatile memory.
