ELECTRONIC DEVICE INCLUDING PLURALITY OF MEMORY DEVICES AND OPERATING METHOD OF

Disclosed is a memory system including a random access memory, a memory device, and a processing unit that controls the random access memory and the memory device. Each of the plurality of storage devices includes a first storage area and a second storage area. The processing unit allocates a partition to a first storage area of the storage device. The processing unit allocates RAID stripes to partitions, performs writing of sequential data based on a sequential logical address for each of the RAID stripes, and performs writing of parity corresponding to the writing of the sequential data after completion of the writing of the sequential data. The processing unit writes an intermediate parity corresponding to the parity into a second storage area of at least one storage device among the storage devices while performing writing of the sequential data. 公开一种存储系统，该存储系统包括随机存取存储器、存储装置、以及控制随机存取存储器和存储装置的处理单元。多个存储装置中的每一个包括第一存储区域和第二存储区域。处理单元将分区分配给存储装置的第一存储区域。处理单元将RAID条带分配给分区，针对RAID条带中的每一个执行基于顺序逻辑地址的顺序数据的写入，并且在完成顺序数据的写入
