Abstract: An operating method of a system including a memory-based storage device and a host comprises: a step in which the host receives information of a free space size able to program from the memory-based storage device; and a step in which the host creates parameters in order to control the performance of garbage collection of the memory-based storage device based on the information of the free space size, and transmits the created parameters to the memory-based storage device. The method additionally comprises a step in which the memory-based storage device performs the garbage collection based on a first parameter.

Abstract: PURPOSE: A memory system and a metadata management method thereof are provided to reduce storage time of metadata by recording a divided part of the metadata and log data including changes in a non-volatile memory device. CONSTITUTION: A buffer memory(120) provisionally stores log entry information composing log data and metadata divided into groups. A memory controller(130) updates the metadata stored in the buffer memory and generates the log entry information corresponding to a change of the metadata according to operation generating the change in a non-volatile memory device(140) in order to store the information in the buffer memory. The memory controller stores the log data and the metadata of a sequentially selected group in the non-volatile memory device every time the number of the log entry information reaches a threshold value.

Abstract: PURPOSE: A method of read/write performance of non-volatile data storage device is provided to improve the read and write speed by reading data with sequential read function, even though the data is stored in a random write function. CONSTITUTION: The logs are created after collecting patterns(402). A logical address sequentially read is extracted based on the logs(406). The physical address status of the non-volatility data storage unit where logical address are mapped is checked(408). The logical addresses of data read in sequence are rearrange to be read in an interleaving unit(410). The rearranged data is read in a interleaving mode(412).
