Storage device, controller and operating method of storage device

The invention relates to a storage device that includes a semiconductor memory device including memory blocks, planes which include the memory blocks and memory dies in which the planes are included;and a controller configured to store user data and metadata determined based on a command received from a host, in super memory blocks each including some of the memory blocks. The controller includesa segment queuing circuit configured to queue segments of the user data or the metadata to N (N is a natural number) virtual die queues according to a striping scheme; and a segment storage circuit configured to store the queued segments of the user data or the metadata in a super memory block among the super memory blocks, wherein the queued segments of the user data or the metadata are stored in the memory blocks included in the super memory block, according to a striping scheme. 本公开涉及一种存储装置。该存储装置包括半导体存储器装置和控制器，其中半导体存储器装置包括多个存储块、包括存储块的多个平面和包括平面的多个存储器管芯，并且控制器被配置成将基于从主机接收的命令所确定的用户数据和元数据存储在超级存储块中，每个超级存储块包括多个存储块中的一些存储块。
